1. CIRRHOPETALUM VIRIDIFLORUM, Hook. fil. Ic. Plantar., t. 2061. 
Coespitose; pseudo-bulbs ovoid, often much tapered to the apex, 1 to 1:25 in. long. 
Leaves thin, in pairs on the young pseudo-bulbs, deciduous after flowering time, nar- 
rowly oblong or oblong-lanceolate, the apex acute, the base narrowed, sessile; length 
3°5 to 5 in. breadth 1 to 1:4 in, Scape with an erect peduncle, 3 to 5 in. long, 
sheathed at the base, and with two or three distant sheathing bracts; raceme drooping, 
from 2 to 4 in. long, many-flowerel. Flowers about :75 in. long, drooping, imbri- 
eate; floral braet ovate, acuminate, 3 nerved, longer than the shortly stalked thick 
ovary. Dorsal sepa! ovate-oblong, sub-acute, depressed; the lateral pair less than 
twice as long as the dorsal, dimeliately ovate-lanceolate, eohering from base to apex. 
Petals sub-orbicular, the edges with a dense belt of short purple gland-like hairs. Lip 
longer than the petals but shorter than the dorsal sepal, fleshy, entire, oblong, blunt; 
the edges of the grooved lower half up-turned. Column with large broadly falcate 
hooked (inverted hatchet-shaped) apical processes, the foot short. Ат? е” helmet-shaped, 
papillose ; pollinia very unequal, the outer two narrowly reniform. Hook. fil Fl. Br. 
Ind. V, 779. 
Sikkim, at elevations of 5,000 to 7,000 feet; common; Pantling, No. 99; in flower 
during October and November. Khasia Hills, at Shillong; аҚ, 5,000 feet; C. B.

The sepals of this are оға dull yellowish-green colour, changing to pale warm 
brown at maturity; the floral bract is straw-coloured, and the rest of the flower more 
or less purple with white blotches. In general appearance and coespitose habit it 
resembles C. refractum, having like it leaves in pairs, drooping racemes and dull greenish- 
yellow sepals. But the long upper sepal (more than half as long as the lateral pair) 
suggests Bulbophyllum, from which genus Cirrhopetalum is separated by only arbitrary 
and not very constant characters. 
Prate 118. Cirrhopetalum eiridiflorum, Hook. fil. А plant, of natural size. 1 Flower with 
its bract, front view, 2 stalked ovary, column and lip, seen from the side, 3 floral bract, opened 
out, 4 the petals, 5 lip, 6 anther, 7 column showing its large hooked processes, papillose anther 
in situ, and short foot, 8 pollinia; ай enlarged.
