244 NOTES ON THE FLORA OF CEYLON. 



3 small projecting teeth ; spur short, blunt, flattened, slightly 

 curved ; column short, prolonged below, winged, white with claret 

 dots ; capsule broadly or roundish-ovoid. 



Hab. Common on tree-trunks in the higher hill-forests, as 

 about Kakgala, whence the specimens named by Thwaites were 

 collected, Oct. 1866. (C. P. 3926 in Hb. Perad.*). 



A small but rather pretty little species, the flowers about | in. 

 across, slightly nodding. It appears to be near D. micruholhon A. 

 Eich. [D. hinnile Wight Ic. t. 1643), which has, however, larger and 

 more numerous flowers of a different colour, and with a sharp spur. 



Bulbophyllum crassifolmm Thw. ms. — Small ; pseudo- 

 bulbs small, numerous, about the size of a pea, nearly spherical, 

 smooth ; leaves solitary, ^-f in. long, sessile, very fleshy, oval, 

 obtuse, the midrib marked by a furrow above ; flowers solitary, 

 each on a very short peduncle in the sheath of a short truncate 

 bract ; sepals nearly equal, broadly ovate, the upper one erect, 

 arched, the lateral ones spreading, yellowish green, densely and 

 minutely j)unctate with red ; petals minute, broad, truncate ; 

 labellum very small, tongue-shaped, obtuse, white. 



Hab. On the trunk of a tree, Kukul Korle, Western Pro v., 

 Sept. 1865. (C. P. 3879 in Herb. Perad.). 



A very small and inconspicuous species, of which I have only 

 seen the herbarium specimens above described. Belongs apparently 

 to the elegnns section, but remarkable for its very small solitary 

 flowers. The leaves are dark green, and very like those of some 

 Hoija. The above description is principally taken from a MS. note 

 of Dr. Thwaites. 



Cleisostoma Thwaitesianum Trim. — C. maculosa Thw. 

 Enum. p. 304, non Liudl. — An C. decipiens Lindl. ? — Leaves large, 

 8-10 in. long by 1 in. or more wide, distichous on the short stem, 

 obliquely emarginate at apex, thick, flat, dotted with minute purple 

 spots beneath, especially near the base ; inflorescence 2-6 in. long, 

 unbranched or with a few slender curved ascending branches ; 

 flowers small, numerous, sessile ; sepals and petals nearly alike, 

 half-spreading, oval or oval-oblong, subacute, lemon-yellow, with 

 large vinous-red stains ; labellum small, broader than long, entire, 

 paler yellow ; spur short, broad, blunt, gibbous ; capsule about 

 ■J in. long, linear oblong, ribbed ; seeds golden-yellow. • 



Hab. Not an uncommon orchid on trees in the moist low 

 country. The specimens described were collected at Heneratgoda, 

 Western Prov., in February of the present year (1885). (C. P. 3193 

 in Herb. Perad.). 



Mr. Bcntham, in Gen. Plant, iii. p. 581, has pointed out that 

 this plant is not the C. nua-ulosiim of Lindley (to which he refers 

 the Ceylon plant called by Thwaites Saccolabiuiii iincolatum), but 

 seems to be a new species near C. WemUandonnn Echb. f.f 

 Bentham states that he had not seen specimens, but only a drawing ; 

 this, however, if as I suppose a copy of the one in the Herbarium 



* Sj^ecimens are also to be found under C. P. 2353 mixed with those of 

 I). iHinduratum Lindl., which it a good deal resembles, 

 t I have not seen the description of this species.
