The interesting terrestrial Orchid here figured is a 
native of the Eastern Himalaya and the Khasia Hills, 
where it is met with in forest at elevations of 5,000 to 
7,000 feet above sea-level. It was originally described 
by Lindley, eighty years ago, from herbarium material, 
as Anoectochilus lanceolatus, but having been found by 
Mr. Bentham to belong rather to Blume’s allied genus 
Odontochilus, which differs from Anoectochilus in having a 
bilobed globose sac in place of an oblong spur, in the 
details of the column and in having leaves that are not 
reticulately veined, it was transferred to Odontochilus by 
Aprit-J ung, 1918,
