TROPICAL HIMALAYA, from Garwhal eastwards; the KHASIA, NAGA and 

 MUNNIPOEE HILLS, BUEMA and the DECCAN PENINSULA to TRAVANCORE. DISTRIB. 

 China, Malay Islands. 



Stem 2-4 ft. ; tubers 3-4 in. long. Leaves 2-6 in., imbricating up to the 

 flowers, upper cucullate. Raceme 3-5-fld. ; bracts leafy ; flowers 3-4 in. diam., sub- 

 sessile, white, fragrant; sepals spreading, lateral obtuse, dorsal very broad rhomboid 

 spreading; petals small ; side lobes of lip truncate ; midlobe linear, or dilated down- 

 wards ; anther very broad and large, cells slightly divergent, tubes adnate to the 

 sides of the column ; pollinia linear, about as long as their caudicle ; stigmatic sur- 

 faces obscure ; rostellum confluent with the face of the column. This is a true 

 Platanthera, in wanting the produced stigmatic processes, and the obscure rostellum, 

 which is marked by a triangular line only.
