A beautiful little plant, easily separated from all its allies by its small size, narrow 
leaves, slender peduncles, and usually purple flowers. An interesting account of an 
attempt made by Captain Dorrien-Smith to introduce it into the British Isles is given 
in the Kew Bulletin for 1910 (pp. 120-26), and should be consulted for information 
respecting the habitat and life-history of the plant. ?
