North India up to 4,000 feet elevation; South India, Western 

 mountains 2,000-4,000 feet; Malay Peninsula. A very i distinct 

 looking plant in its typical form at low elevations, but running it to 

 elongata at higher elevations {vide forms of my collecting on the 

 Nilgiris and Brumagherries in the British Museum).

 This has much the aspect N ot 

 odontolonia, and it will pro-
