504 NEOTTE/E—PHYSURIDJ. 
A plant with the habit of a prostrate Commelina. Leaves about an inch 
long, gradually diminishing into the scales of the scape, which in this 
species is not distinguishable from the stem. The hairless sepals are a 
remarkable character in a genus so generally hairy. 
A figure of this exists among the collection of M. Descourtilz, who says 
he only found it at the foot of trees half destroyed by fire, and whose 
decaying fragments form the vegetable mould that surrounds them, He 
describes the appearance of the whole plant as being crystalline like 
Purslane.

Hab. in India orientali; provincia Sylhet, Wallich; Zeylond, locis obum-

From 1 to 2 feet high, the upper part covered with a brownish down, 
the lowest quite smooth. The flowers are dull brown, a little tinged with 
pink, and are closely pressed into a long spike. 
If the labellum of Erythrodes latifolia is really emarginate and rounded 
at the apex, as it is described and figured, it must be diíferent from this ; 
but the description and figure given by Blume accord so well in other 
respects that I suspect an error in that particular.
