Of this plant I have only seen two dried specimens, collected near 

 Serampore by Haloodar, the very intelligent gardener of the late Dr. 

 Carey's garden. It appears to be represented by a drawing in the 

 Library, bearing the name of Habenaria Vicaryi, but of which I have 

 obtained no other information than that it was procured from Capt. 

 Vicary, probably from Goruckpore. It seems to be allied to Habenaria 

 digitata.*
