Between Mannampitiya and Gunner’s Quoin. 
The meaning of the Sinhalese name is given by Spittel (Wild Ceylon 
p- 195); his plant, however, sounds like an orchid, perhaps a species 
of Habenaria, and he speaks of a red variety w hich is unknown to 
me. The Mannampitiya specimens were called Thungai-kolai by the 
villagers and were not in flower.
