Shan hills at 4400 feet, H. Manders. 
This resembles H. alata, Hook., a West-Indian species which 
has two small lateral teeth to the labellum and a much shorter 
spur, and it seems to be quite alone among the Asiatie species 
with elongated stigmas and anther-cells in having a small entire 
labellum. 
Habenaria ($ Peristylus) monophylla, Coll. et Hemsl., n. Sp- 
Planta graciliuscula, circiter pedalis, per totum fere pubes- 
cens, unifoliata, infra folium paucivaginata, scapus infra flores 2- 
3-braeteatus. Folium crassiusculum, latum, scapum laxe in- 
volvens, marginibus late obtegentibus, obseure multinervium, vix 
acutum, utrinque pubescens, minute ciliolatum. Flores sub-

subæqualibus erosis, calcare puberulo sepalis dimidio longiore 
crassiusculo recurvo basi conspicue inerassato; columna parva, 
antherarum loculis non elongatis, stigmatibus parvis; ovarium 
pubeseens. 
Shan hills at 4000 feet. 
In floral structure this resembles several species, but the 
general hairiness of the plant, associated with the solitary leat 
and small flowers with a broadly three-lobed lip, sufficiently 
characterize it. The Sikkim ZH. unifolia has an undivided lip.
