Pseudobulbs short or elongated into a naked or sheathed vermiform cylindric 
stem, 5-6 in., and as thick as a pencil, at first sheathed. Zeaves 4-6 in., subovate, 
rigid. Spike shorter; flowers glabrous, white; mentum rounded; lip very variable 
as to ridges, &c.; its spreading and recurved side lobes are a good character.—A 
drawing (in Herb. Hort, Cale.) of a Sikkim plant which may be a form of this has 
small side lobes of the lip pointing upwards, a ridge on the centre only of the midlobe, 
and two calli? between the side lobes, The habit is entirely that of graminifolia.

drawings in Herb. Hort. Caloutt.

.Pseudobulbs 1-2 in. ovoid or subcylindric, never much elongate. Leaves 5- 
6 M., sessile, rigid, lanceolate. Spike few-fld.; very short pedicel with ovary 
In.; flowers white, lip yellow with pink side lobes and very strong purple nerves, 
;* Saccate.—The only species of this group with basal spreading side lobes of the 
IP. Wallich’s No. 1974 consists of flowering specimens of this, and flowerless of 
3 Confusa (which has not an excavate column); but in the distribution of his 
erbarium, indley received flowering specimens of confusa only, the character o
