PREFACE.

Tuis work, which has been ten years in execution, would have been long since brought to a close had the subject been less diffi- cult, or one which demanded less exact examination. It has, how- ever, proved a most laborious task to examine with the necessary care so large a number of plants of a very intricate structure, in a dried state; and the author's other engagements have left him little leisure for the steady prosecution of this enquiry, so that it has been impracticable to advance with greater speed.

This explanation is due to those friends of science whose collec- tions have been entrusted to the author for all this long period. He regrets, however, to add that, during the ten years that have elapsed since the appearance of the first part of the work, his materials for the classification of Malaxez, Epidendrez, and Van- deze, have so much increased by the acquisition of species in his herbarium, or by the introduction of living plants to the gardens of Europe, as to render a reconsideration of those tribes indispen- sable. This will take place in a Revision of the Order, which is even now in preparation, and which, if his life is spared, may be expected to appear about two years from this time, illustrated with numerous figures of genera. In that work will be incorporated all the author's recent acquisitions, with such others as, in the mean- while, may be sent him; and an attempt will be made to sub- divide the other tribes, upon the same principles as have been adopted in the classification of Neottez. ‘The author will be very grateful for assistance; but he finds it necessary, in consequence of the great numbers of dried plants sent him for determination, to be returned to the owners, to condition that, from this time for- ward, with the exception of those in his hands at the present time, he shall not be expected to return the dried plants, which his correspondents may send for names, but that he shall have full

liberty to incorporate them with his own herbarium, unless some express arrangement is made to the contrary. For it is unjust that he should sacrifice his time to this kind of enquiry, merely to satisfy the curiosity of those who are unable to determine Orchidaceous plants for themselves. The author will, however, in all cases quote in the intended ** Revision" of the order, the numbers attached to the specimens sent to him and preserved by him; so that if those, who are so obliging as to communicate them, will preserve dupli- cates with similar numbers, they will be able, when that work appears, to ascertain what their plants have proved to be.

In the prosecution of his task thus far, the author has received from numerous quarters most essential assistance. He is, how- ever, still in great want of communications from some parts of the world, as will be seen by the following geographical arrangement of the evidence upon which his knowledge of species has been formed.

EunoPEAN species have been supplied by many. botanists, espe- cially by the late Baron Jacquin, Professors Tineo and Tenore, Dr. Hornschuch, and Messrs. Bentham, Talbot, Strangways, &c.

Those of SIBERIA and NonrHERN Asia were furnished by the late lamented Mr. Prescott, whose access to Russian herbaria enabled him to procure several species, of which nothing has been seen elsewhere. Materials have been also communicated by Dr. Fischer, Professors Ledebour and Bunge, and others; but more information is still required for the species of the Southern pro- vinces of Russia, and of the more easterly provinces of thal power in Asia.

Of Nortn American species there are few which have not been carefully examined. "Those of the United States and Canada have been given to the author by Mr. Menzies, Drs. Torrey, Asa Gray; and Booth, and by Sir W. Hooker; others have been purchased. In addition he has examined the valuable collections formed in Cali- fornia and North West America, for the Horticultural Society, by Douglas, and in Texas and Carolina by Drummond. For Mexican species considerable materials have been furnished by the ample collections of Karwinski, in the Royal Museum of Munich; of Deppe and Schiede, communicated by Professor Schlectendahl; of Hartweg, and others; and by the large importations of living plants into this country. But a considerable number of species

described by Llave and Lexarza, have as yet escaped observation, and remain for future determination.

is greatly needed.

Information concerning them

i i

PREFACE. vii

For CENTRAL America the materials at the disposal of the author have been less copious, considering the great richness of those countries in plants of this natural order; and yet they have been considerable. The species of Peru, collected by Mathews, of Quito and the Quitinian Andes gathered by Professor Jameson and the late Col. Hall, and preserved in the herbarium of Sir W.

. Hooker, and a few others have yielded the greater part of the in- formation in the possession of the author; for the difficulty of com- munication between England and these parts of the world, for the present, forbids the acquisition of many species in our gardens. It will, therefore, be found that many of the species of. Humboldt and Bonpland, of Henke, Póppig, and the authors of the Flora Peruviana, still remain to be examined by the author. Of the latter, however, a portion has been found in the collection of Mr. Lambert.

The East coast oF EQUATORIAL AMERICA and the West INDIES are more completely investigated. Our gardens are rich in species from those parts of the world, and herbaria are less deficient in them. A great quantity of information has been furnished by the collections of Mr. Schomburgk in Tortola and British Guayana; of Martin in French Guayana, for whose plants the author is indebted to Mr. N. B. Ward, and of various Botanists in differ- ent parts of the West Indies. There are, however, many of the old species of Swartz, about which no evidence seems to exist in this country; for it is certain that the Flora of Jamaica is less known to Botanists of the present day than that of India. Few collections of dried plants would present greater botanical interest now than those of Jamaica and St. Domingo, from the mountains.

For the Brazittan Fiora the author has had the advantage of consulting the large collections brought home by Dr. Von Martius, and the drawings by Descourtilz in the possession of Baron Ben- jamin Delessert; but, unfortunately, both these sources of informa- tion were supplied after the publication of the Vandeée; great additions have, therefore, still to be made in Brazilian plants to both the genera and species of Malaxew, Epidendrez, and Vandce, all which will be introduced into the “Revision” already alluded to. Fortunately, however, our gardens are particularly rich in Brazilian Orchidacez; and the collections of Salzmann at Bahia, of Forbes, Douglas, G. Don, Macrae, Gardner, and other travellers, together with specimens brought home by Russian botanists, and procured for the author by Mr. Prescott, have placed à considerable mass of materials within the author's reach.

Vili PREFACE.

Cute and the parts of SOUTH AMERICA BEYOND THE TROPIC have .

been well investigated by Douglas, Cuming, Mathews, Cruckshanks, Bridges, Tweedie, Gillies and others, all of whose collections have been carefully studied ; but there are many of the species mentioned by Poppig, which the author has never seen.

The NonTH or Arrica possesses few species of this order not common to the South of Europe, Salzmann's collections from Tangiers, Dr. Leman's in Madeira, some kinds met with by Bové near Algiers, and Mr. Webb's Canary herbarium have furnished the author with the greater part of them.

His knowledge of the species of Tropicat Arrica is principally derived from plants found by G. Don at Sierra Leone, a few from Cape Coast Castle and the Isle of France in the Herbarium of Sir W. Hooker, some Madagascar species gathered by Dr. Lyall, and preserved in the same rich magazine, and from the English gardens, where several have from time to time produced their flowers. The author has not, however, been so fortunate as to meet with much to elucidate the obscure species of Du Petit Thouars, from the Isle of France, Bourbon, and Madagascar, and he earnestly solicits assistance with respect to those islands.

Of Care species his examination has been pretty complete. The beautiful plants found by Mr. Drége and most admirably preserved, have been placed at his disposal by that liberal botanist; besides which he has been able to study the species of Dr. Burchell, communicated by himself, of Mr. Harvey, of Forbes, of Ecklon, and of some of the older collectors preserved in the herbaria of Vahl, Hornemann, and Lehmann, for which he has been indebted to the two last eminent naturalists.

In the WARMER PARTS OF Asia, copious materials have been furnished. Ceylon species in abundance were communicated by the late Mr. Macrae, besides which the herbarium formed by Col. Walker in that island has been consulted. The vast collections of botanists, travelling under the patronage of the East India Com- pany, have been most liberally given up to unrestricted examination by the Honourable Court of Directors of the East India Company ; besides which the author has been largely indebted to the private

friendship of Drs. Royle, Wallich, and Wight, and of Mr. Griffith. :

By these means the Flora of the Himalaya, of a great part of Hindostan, of Burma, Assam, and some parts of the Malayan Archipelago, has been extensively incorporated in this work. -Jt is, however, a subject of great regret to the author that the

PREFACE. ix

Orchidacee of Java, Sumatra, and the Philippines, countries so peculiarly rich in those plants, should at present be comparatively unknown to him. Many Chinese specimens have been obtained through the Rev. Mr. Vachell, who sent his plants to Professor Henslow, of Cambridge, and from Mr. Reeves; but of (hat country and Japan very little can be said to be known.

The Orchidacee peculiar to New Horrawp were carefully examined by Dr. Brown and Mr. Ferdinand Bauer during Flinders's Voyage; and the author has been so fortunate as to be favoured with authentic specimens of some of them from Dr. Brown him- self; he has also been kindly furnished by Dr. Endlicher with tracings of most of Mr. Bauer's drawings preserved in the Imperial Library at Vienna; and he has received materials from the late Mr. Allan Cunningham, the Council of the Linnean Society, Mr. Everett, Sir Thomas Mitchell and others. It is, however, to the collections of Swan River plants formed by Mr. Drummond, and most especially to a very large quantity of Tasmannian specimens, most liberally furnished by Mr. Gunn, that the author is indebted for means of examining the Orchidacez of Australia, as is amply testified by the references in the following pages. There are still, however, many species from the East and North Coast, with which he has no acquaintance. ;

New ZEALAND is as yet almost an unknown land with respect to Orchidacexw. Species from that island or from any parts of the Pacific will in all cases be particularly welcome.

In an order like this, so peculiarly intricate in the structure of the organs of fructification, collections of dried plants would be of little value, in the absence of that kind of knowledge which can only be obtained from the study of living species. For the latter the author is so extensively indebted to the friends of science in this country, that to acknowledge his obligations particu- larly, would be to publish a list of all the principal gardens where such plants are cultivated in Great Britain. lt would, however, be unjust not to mention the names of his friends, the Messrs. Loddiges, as the most constant of all his correspondents, and as those to whom he has been indebted during many years for a continual and most abundant supply of beautiful living specimens of the utmost rarity. 'The large quantities of plants sent him by James Bateman, Esq., the author of the noble work on the Orchida- Cee of Mexico and Guatemala, and by George Barker, Esq. of Birmingham, the possessor of an invaluable collection of Mexican

and other species, chiefly imported by himself, will also justify the author’s expressing his particular obligations to those gentlemen.

It is only necessary to add that the total number of species included in this work amounts to 1980. Of those which are regarded as well established species the author has analyzed the organs of fructification of more than three fourths.

The general structure of Orchidaceæ, briefly embodied in the foregoing description, has been treated of at such length in the prefatory matter of the Illustrations of Orchidaceous Plants, that it is unnecessary to do more than refer the reader to that work. I must, however, take the opportunity of correcting one part of the theoretical view which was there taken of the structure of the column. While, in common with Dr. Brown, I regarded the stigma as really consisting of three parts, usually in

* This occurs only in the obscure plant c is by Du Petit Thouars, of

a state of confluence, I also supposed the position of the stigmata to be opposite the petals ; being led to that conclusion by the constant position of the stigmatic arms of Ophrydz. That opinion I now retract, in con- sequence of the position of the stigmata in Cypripedium, which C. specta- bile shews most clearly to be opposite the sepals; and therefore the stigmatic arms of Ophryde are to be understood as side lobes of that stigma which is opposite the dorsal sepal. This circumstance, however, only con- firms the accuracy of my view of the true nature of the stamens, which are certainly all opposite the lobes of the stigma in Cypripedium.

While, however the untenableness of my first opinion, concerning the relation borne by the stigmata to the other parts of the flower, is thus admitted, there remains a difficulty that opposes itself to the view I now take in common with Brown, and which must not be overlooked. It is that the placentiferous pieces of the ovary are not opposite the stig- mata, but alternate with them, ‘while the seedless pieces of the ovary are ina line with the stigmata! This seems to show that the ovary is composed of 6 carpellary leaves, of which three bear stigmata without ovules, and three bear ovules without stigmata. However paradoxical this may appear, it is by no means incompatible with the due perform- ance of the functions of impregnation; for the carpellary leaves do not adhere into a solid mass, either in the ovary or in the style. On the contrary they form a cavity open from the stigmatic apex down to the ovules, and the whole of that cavity is lined with a lax conducting tissue, which may nevertheless be exclusively furnished by 3 stigmas only, and may become so confluent with the placente as to form a perfect channel of communication for the pollen tubes in their descent into the ovules.

The order owes its chief peculiarities to the following circumstances : Jirstly, to the consolidation of all the sexual organs into one common mass, called the column ; secondly, to the suppression of all the anthers, except one in the mass of the order, or two in Cypripedee ; thirdly, to the pecu- liar condition of its pollen, and the anther which contains it ; and fourthly, to the very general developement of one of the inner leaves of the perianth or petals in an excessive degree, or in an unusual form. These peculiarities are in most cases so striking, and all so strongly nranifested in the same flower, that the inexperienced botanist may be unable to discover their real character. We find, however, that the true nature of each part is indicated by special cases of structure occurring in different parts of the order.

Thus in Cypripedium not only are two lateral stamens furnished with anthers, while the central stamen is antherless, but the stigma and style Separate from the filaments nearly to the base, and the triple nature of the former is distinctly shown, together with the relation of its lobes to the other parts of the flower. The pollen, which has so anomalous an appear- ance in its waxy or sectile state, presents the usual appearance of that substance in Goodyera, and many Neotteze. And the irregularity of the labellum disappears in such genera as Thelymitra, Paxtonia, Macdonaldia,

Hexisea, and some others, whose flowers are almost as regular as those of a Sisyrinchium.

se is indeed to the latter genus, more nearly than to any other, that rchidaceze seem to approach in structure, except to Zingiberaces ; so

- *

xvi

that they may be supposed to pass into Iridacez through Thelymitra and Sisyrinchium on the one hand, and into Zingiberacez through Phrynium and such a genus as Evelyna * on the other.

With regard to Apostasiacee, their relation to that order does not appear to me to be greater than to either of the two now mentioned ; and in the absence of all evidence as to the connecting links which join Orchidacez and Apostasiacez it seems unnecessary to advert further to the subject. It may, however, be observed that Apostasia has apparently as much claim to be regarded as a diandrous monadelphous Amaryllidaceous plant allied to Hypoxide and standing, perhaps, in the same relation to that order as Gilliesia to Liliacez, as it has to be regarded as a trilocular Orchidaceous plant with the gynandrous organization lost.

In classifying this order the most important characters appear to reside in the pollen, which in many is consolidated into firm waxy masses of a definite number in each species, and in others is either in its usual /oose powdery condition, or is collected in granules or small wedges the number of which is far too great to be counted.

Of those with waxy pollen masses some (MaraxEz) are destitute of any visible processes by which the masses are brought into contact with the stigma ; others (ErrpENDREx) have strap-shaped caudicule, which are either bent down upon the masses themselves, or serve to hold them together, without, however, forming any organized union with the stigma ; whiie the remainder (VaxpEx) have a caudicula, which adheres firmly to a gland found on the upper margin of the stigma and separating freely from that organ. The last form is much more distinct from the two first than they are from each other, and I am inclined to think that hereafter it will either be requisite to combine Malaxee with Epidendrez, or to exclude from the former not only Acanthophippium, Celogyae and Pbolidota, but several other genera at present referred to them.

The genera with powdery, granular, or sectile pollen cannot be classified so conveniently by modifications of that part, but are readily divided into 3 natural tribes by peculiarities in the anther. In some (Ornunrsz) the anther is erect, not hinged to the column but continuous with it, and stands above the stigma, the pollen masses having their points directed to the base of the lobes of the anther ; in others (AnETRHUsEX) the anther is hinged to the column, upon the end of which it is placed transversely like alid; and in others (NEorrxx) it is also hinged to the column, but is stationed at its back so as to be nearly parallel with the stigmatic surface.

If to this we add that Cypripepex have two anthers, while all the

others have one only, we find the order divided into seven tribes, of which the following is a tabular view.

Tribe I. MaLaxIpEz.

ORCHIDEE, Tribus MALAxIDE#. Lindl. Coll. Bot. Orch. Scel.

Pollen in massis cereaceis (polliniis) definitis cohzrens, telA omni cellulos& superflua ademptà. Anthera terminalis, opercularis. Herba epiphyte v. terrestres, foliorum basibus v. caulibus sæpiùs incrassatis.

_I comprehend in this Tribe all the genera that have their pollen cohe- ring in masses of a firm waxy texture, without any of the cellular sub- stance, by which the grains are connected, remaining under the form of a distinct gland lying upon the stigma, or of an elastic transparent com- munication (caudicula) between the pollen masses and the gland. Ma- laxidez may, in other words, be considered as Orchideous plants, the pollen of which communicates directly with tbe stigma, without the intervention of any intermediate apparatus.

Dr. Hooker's figure is authority for this species, and it is from it that I have framed my specific character. It is extremely probable that more species than one are confounded under the same name. Ihave specimens from Rio of what is no doubt nearly allied to this, but which differs in the form of the leaf, and in having a ciliated Labellum ; my specimens are not good enough to describe. |

This genus forms a transition from Pleurothallee to Dendrobiee. The differences between it and Eria will be noticed in speaking of the latter genus, to which I have to add the remarkable circumstance of all the pollen masses being collateral and not lying in pairs upon each other, a fact which I have learned from Mr, Bauer's elaborate drawings. Dr.

Ooker's figure in the Botanical Magazine, t. 2764, is at variance with

this statement ;—but I presume that excellent Botanist's specimens were

This species and the foregoing so entirely resemble each other in habit, foliage and inflorescence, that it is in vain to seek to which of them the specific name graminifolia may with the greatest justice be applied. Mr. Brown's specific character is equally applicable to both, and any Botanist might be liable to confound them when dried. I have therefore retained the name for the species figured by Dr. Hooker, who may be considered as the first who really established the species with precision.

I do not think there are any materials in this country sufficient for de- termining exactly what the Malaxis Rheedii of Swartz is, or rather the Basaala Poulou-Maravara of the Hortus Malabaricus upon which that species was founded. Of a Microstylis from India answering to Rheede's figure I have seen no specimen. "The Epidendrum resupinatum of Forster which is referred to it as a synonym, exists in the Banksian Herbarium, and there is also a drawing of that species in the same collection, and these agree extremely well with the Hortus Malabaricus figure: but they are undoubtedly distinct from M. versicolor in their greater size and much larger oblong-lanceolate leaves. Their flowers I have not analysed, but if the Crepidium Rheedii of Blume belongs to Malaxis Rhedii, which I scarcely doubt, the flowers are essentially distinct also.

This genus differs from Liparis chiefly in the shortness and straightness of the column connected with a three lobed concave erect or excavated lip, which is scarcely recurved about the middle, and which has never any tubercles at its base. The column of Liparis is always arcuate. From Microstylis, with which it agrees in the shortness of the column, it is distinguished by its lip being parallel with the column, not at right angles with it, and neither sagittate nor cordate at the base.

"Their real number and position were first made known to me by Mr. Bauer's drawings; the position in which the pollen masses lie, one upon the other instead of side by side, gives them the appearance of being 2 instead of four, and caused the error here ad- verted to.

I was formerly of opinion that the Brazilian and Indian plants were dif- ferent; but more recent observation and the inspection of Dr. Wallich’s Indian drawings have induced me to combine them. I presume there is no doubt of the plant in the Garden of the Horticultural Society, from which L. elata was originally described, being really of Brazilian origin ; and yet it is undoubtedly possible that there may have been some trans- position of labels. I do not adopt the older specific name of bitubercula-

tum because it is expressive of a character common to every species of the genus. .

I formerly called this by the specific name given to it by M. Du Petit Thouars under the genus Malaxis, being at that time unacquainted with any others with the same remarkable distichous inflorescence. More being now known, I avail myself of the privilege which an author undoubtedly possesses of altering his own names if he thinks fit, although no one else can be suffered to do it for him.

_ This singular plant when properly examined will possibly be found dis- tinct from the genus in which it is now placed ; all that I have been able to ascertain satisfactorily, from the inspection of a single mutilated flower, 1s that the pollen masses are as I have described them, and that the plant

elongs to Malaxidee. The peculiar winged rachis and carinate bractee forming a kind of pectinated inflorescence is exactly that of L. gregaria, disticha and some others ; but the plant differs from them in having no ten- dency to form bulb-like stems, in room of which it has the taper woody rooting stems and coriaceous distichous leaves of Aerides and its allies.

I learn the very curious structure of this plant from a beautiful sketch of Mr. Bauer’s. Its peculiarity consists in its anther having its lobes con- nected by only a narrow slight connectivum, so that it is twolobed, and in the pollen masses being concave and convex so that each pair forms a sort of hollow body narrower at the back than at the front, at which end it is open. The placentary angles of the ovarium are larger than the rest and simple, while the intermediate ones are smaller and double.

In this genus there are some species in which the rhizoma has spurious bulbs, and others in which, in lieu of these bodies, the joints of the rhi- zoma themselves become fleshy. The anther is not formed upon the usu plan of Orchidee. Instead of the valves opening by two slits along the face of each lobe of the anther, these lobes are combined and the whole face of the anther separates from the back, on which account I have call

it bilabiate. The same thing appears to happen in some of Blume's Che lonantheras.

Obs. This genus is nearly related to Cymbidium among Vandee and to Cattleya among Epidendrez, from both which its peculiar habit is alone sufficient to distinguish it, From Dendrochilum it is only known by the absence of horn-like processes from its column ; for the lip of some of the Gomphostylis section is entire, and C. (Panisca) parviflora is a Dendro- chilum in every thing except the want of these processes. "There isa strong tendency to produce a gland in some species such as C. praecox, uniflora, and fimbriata ; but this is a mere granular mass such as the filum Y Epidendrez and will not be confounded with the cartilaginous gland of

andez.

In this species it appears from Dr. Wallich's figure that there is a pro duction at the base of the pollen masses, indicating I presume from its colour a formation of granular matter as in some other species that I have examined. It is nevertheless possible that the artist may have intended

to represent a cartilaginous gland, in which case the species would be rather referable to Cymbidium. I have seen no specimen.

Racemi radicales.

I have no hesitation in referring all the above cited genera hither. When I published Tribrachia I was only acquainted with Bolbophyllum through Du Petit Thouars’s figures; I now know them to be the same. Diphyes is obviously a synonym. Dr. Hooker's Anisopetalum differs only in the greater inequality of the sepals. Even Cirrhopetalum itself is less

distinct from Bolbophyllum than would appear from the inspection of the lst and 2nd species.

This is the handsomest species of the genus and is remarkable for its large globose pale yellowish green flowers spotted with purple. Dr. Wal- lich's description in the work above quoted is excellent. :

This species is nearly related to the preceding, with which it agrees in the position and size of its flowers, but it differs from it in their being solitary, in the more lanceolate figure of the floral envelopes, and especi- ally in the petals being as large as the sepals ; a solitary case in this genus. 3.

I know this very remarkable plant only from an excellent drawing in Dr. Wallich's possession. It is not more remarkable for its very A imbricated flowers, which have a great spathe-like bractea at the base 0

their spike, than for the want of the spurious bulbs, which are, with this single exception, characteristic of the genus.

For my specimens of this very curious little plant I am indebted to the Horticultural Society, who received it from Mr. Forbes. It has the smallest flowers of any Orchideous plant I know ; it grows upon the young branches of trees covering them with its numerous thread like roots. It appears to be leafless.

I suspect that Angraecum aphyllum of Du Petit Thouars, t. 73. belongs to this genus.

This genus is essentially distinct from Octomeria, in having the lateral sepals very oblique and connected with the elongated base of a short co- lumn, of which the foot is much longer than the column itself; and also in habit. Eria is a genuine genus of Dendrobiee with the column incumbent upon the ovarium ; Octomeria on the contrary must be consi- dered, notwithstanding the slight elongation of the base of its column, to belong to the genera characterized by the column being continuous with the ovarium. In Octomeria the sepals are of equal size; in Eria the lateral sepals are much larger than the upper one.

I formerly thought that the characters by which the following species is distinguished were of sufficient importance to justify me in separating it from Eria as a particular genus, for which I accordingly adopted Dr. Hamilton's manuscript name of Pinalia. Subsequent experience has how- ever led me to doubt the value of these characters unconnected with other differences, and I have accordingly reduced the genus to a subgenus of Eria. I may however observe that the degree of developement of the viscid matter by which the pollen masses cohere is greater in Pinalia than in any other Malaxideous plant with which I am acquainted, and that it exhibits an instance of a near approach to the cartilaginous gland of Vandee.

I know this genus chiefly by Blume's figure and description. It seems to differ from Aporum in nothing but having two pollen masses instead of four, and in the presence of a tubercle below the tip of the lip on the under side. I have not been able to satisfy myself upon the first point, in exa- mining the flowers of Dr. Wallich's specimens of O. carnosum ; but I presume Dr. Blume's observations, made upon fresh flowers are accurate as to this.

1. OxysTorpHyLLUM carnosum. Blume.

I originally considered this a species of Aporum, not having been able to procure any flowers; the examination of one or two withered blossoms has since enabled me to ascertain that it is the Oxystophyllum carnosum of Blume. Rumphius's figure is characteristic.

When I published the type of this genus in my Collectanea Botanica, in 1821, I had seen only imperfect pollen masses ; one lying in each cell 0 the anther. Subsequently Dr. Hooker, in founding the genus in his Exotic Flora, represented them adhering to a common pedicel and gland, 4 in num ber, and not lying side by side, but upon each other. Finally M. Achille Richard, in his account of the Mauritius Orchideous plants, states the number of pollen masses to be 2, without any stalk or gland. All these observations are however inaccurate, as I have recently satisfied mys¢

MALAXIDE JE. DENDROBIEJE. 73

from an examination of good specimens sent from Ceylon by Mr. Macrae. The pollen masses are in reality 4 in number and lie loosely side by side, two in each cell of the anther.

I refer this and the succeeding to Polystachya chiefly on account of their habit, It is however by no means clear to me what they really are. M.

There is also some peculiarity in the attachment of the pollen masses to the stigma which requires more investigation.

The most genuine form of Dendrobium is no doubt that of having ca lescent stems with fascicles or racemes of membranous coloured flowers; but there are insensible gradations from this into rhizomata having false bulbs, and there are also species in which the flowers are by no means conspicuous.and rather fleshy. From Bolbophyllum it is distinguished readily by its lip being always sessile, never unguiculate as in that genus and also in the texture of the same part being almost always of nearly the same consistence as the sepals, while in Bolbophyllum it is always re markably fleshy.

It appears to me that Blume's genera which I have here reduced f? Dendrobium, have no characters to distinguish them ; unless Sarcostem? be kept apart on account of a slight peculiarity in its pollen masses the

nature of which however I do not well understand. § I. Rhizoma pseudo-bulbos gerens apice foliosos. _Bolbophyllis proxima. 1. Denprosium amplum. Lindl. in Wall. Cat. no. 2001.

This beautiful species approaches nearer to the genus Bolbophyllum than any with which I am acquainted. Its flowers are not exactly those of Dendrobium, the labellum being shaped differently from what is usual in that genus. It is however comprehended within the definition I have given of it, and will by no means enter Bolbophyllum with which it is its habit chiefly that accords.

This lovely species is abundantly distinguished by its slender stems, leafless, and clouded with dusky brown when in blossom ; and also by its delicate white flowers, the tips of whose segments are remarkably blunt and tinged with delicate violet.

Dr. Wallich remarks in his Mss. that its fragrance is exquisite, not un- like that of Olea fragrans.

The flowers vary in size according to the health of the individual; they also are occasionally seen with the sepals and petals more acuminate than

usual. A variety with stems spotted with purple is known in our hot houses.

There can be no doubt that the plant figured in the Exotic Flora as D. Pierardi, that cultivated in the Botanic Garden at Calcutta under the same name, and the D. cucullatum of the Botanical Register, are all one and the same species. The latter exhibits D. Pierardi in the state in which it commonly appears in our stoves; but whether the flowers appear from among the leaves, or occupy the old leafless stems, depends not upon any specific difference, but upon the state of health of particular individuals.

Dr, Roxburgh says that the leaves of his D.
