182 BURMA, ITS PEOPLE AXD PRODUCTIOXS. 



The result of my observations is much as follows. In all flat-loaved SarcnnflM 

 I find them, and al\va3's 2-lobed, or in some forms bipartite throughout, peiiorally 

 divaricating upwards. I find them also in the three terete-leaved species last 

 described, but here they ditfer in shape from those in the flat-leaved species, though 

 similar in the three ; in all of which (though again not identical in outline) they are 

 of one common type. Tlie upper part is flat, semicircular, and undivided, resting 

 on a narrow slightly bilobed base. 1 find a simihir appendage again in Cleisustoma, 

 hut here it is simply a flat lamina, rounded in outline or more or less quadrate. 

 Tliis, I presume, is the "tooth" to which Lindley alludes in his definition of the 

 genus where he says " calcare denie clauso." I further find an appendage agreeing 

 •with that of Cleisostoina in a small and obscure plant which Prof. Eeichenbach 

 has named " Siiccolnhium lipundatum," but which I had ventured to name 

 Ceratochilus ; and, indeed, whether this genus of Blume be a good one or not, I 

 cannot but think still that it is a Ceratochilus according to his definition, and that 

 it may even be his C. biglandidosm, so remarkably does it agree with his characters 

 at all points. Lastly, the genera T/o'i.rspermuin and Appendicula are also furnished 

 with appendages, but they are either of a diiferent character or in a different position. 



CLEISOSIOili, Bl. 



Plants with distichous leaves, caulescent. The flowers are small and of little 

 beauty. The distinguishing mark is that the baggy spur or pouch is closed by a large 

 projecting tooth, described above, and has no partition. Species 2. 



Bentham, in his "Notes," says, " Aeridcs [Sarcaiifhus) appendiculatitm is a 

 Chisostoma." This may be ; for the group of genera hereabouts is in great confusion, 

 and it needs a master-hand to re-ariange them at once naturally and intelligibly, 

 though, I fear, not a few will steadily refuse all artificial classification ; I say, ' this 

 may S« ' ; but, if so, then I think Sarcanthus filiforrne and <S'. Williamsoni should 

 go along with it, for in both, the callus or appendage which projects into the cavity of 

 the spur, is met by a projecting lump on the opposite side, and thus the entrance is 

 closed. My drawings distinctly show this, for they include longitudinal sections, 

 though I unhappily omitted to make a similar section of <§. appendiculatum. And 

 this closing of the spur by the "tooth" or appendage is of the essence of the genus. 

 Against this, however, is to be set the fact tliat in both these species the .spur is 

 jiartially divided by a membrane, which, again, is said to be the special mark of 

 Sarcanthus, although, once more, in some instances I have not been able to detect 

 this. In all my remarks, I must be understood to speak of Burmese Orchids only, 

 known to myself. 



CAiTAnoTis, Lindh 



A small genus of slender climbing epiphytes, with long narrow linear leaves, 

 and small flowers on leaf-opposed racemes. They have a long rostellum, and a 

 fleshy incurved lip, and have much the appearance of Sarcanthus. C. purpurea 

 is a very pretty species with puiplish-lilac flowers. It must be rare, as I was 

 twenty years in Burma before I found it, and then only one plant. It was dis- 

 covered in Silhet many years ago. C. ohtusa may be described as a ])ale pink 

 variety of tlie same, which is distinguished by having the rostellum or beak tiu-ned 

 at right angles to the column. Species 3. 



Teeisspeemfji, Lour. 



This genus consists of a small number of caulescent epiphytes with distichous 

 leaves, short woody stems, which emit a great number of wiry roots. The flowers 

 are small and few on a rachis, which assumes various shapes, sometimes round, some- 

 times flat, but always more or less swollen and fleshy. The flowers are marked by 

 a 3-lobed lip with a thick and solid middle lobe, articulated with the prolonged 

 montura or base of the column. The pods are long and cylindrical, open longi- 

 tudinally by one valve, and arc full of silky hah' in which the seeds arc enveloped.
