fruits abundantly, and tlius perhaps represents the only species of fucwrcwma 

 which is to be considered as truly spontaneous (see Plate XXX). 



This species, especially the variety "sylvestris" should be compared 

 to C. leucorrhiza, Roxb., which it resembles in many aspects. Most curious 

 is the deflexed midlobe of the lip (see Roscoe (1830) t. 102 fig. 3.) occurring 

 in both species, distinguishing them from other species. Roscoe gives the 

 following description: 



"Spike lateral; plant entirely green; leaves broad lanceolate, smooth on 

 both sides; spikes few flowered; coma pale rosecolour; petals slightly tinged 

 with purple; lip yellow. Bulb ovate; palmate tubers long and straight; 

 pendulous tubers numerous, far spreading, pearly white within ; leaves broad- 

 lanceolate, petiolate smooth uniformly green; plant from 3 to 4 feet high, 

 spike 150—200 mm. high. Fertile bracts green, coma pale rosy. Dorsal 

 corollobe slightly mucronate, all lobes white tinged with purper. Lip white 

 with a purple tinge, yellow and bifid at the apex". 



"A native of the forests of Bahar. Tubers of both kinds are used for 

 preparing a kind of fecule, called Tikhur". 



According to K. Schumann the ovary of C. /ewcorr/z/zo should be smooth.
