|... The colour of the flowers is pinkish or violet, but occasionally they appear to be 
pure white. This plant is to some extent variable, and was described from imperfect 
herbarium material under three specific names by Lindley, but always under the genus 
Gymnadenia. It had originally been referred by him in Wallich's Catalogue (No. 7039) 
to Platanthera. But the latter genus was by Lindley himself finally considered as 
inseparable from Gymnadenia. In dealing, in the Flora of British India, with the 
three Himalayan species of Gymnadenia described by Lindley, Sir Joseph Hooker transfers 
6. spathulata and G. Chusua to Orchis, but he transfers G. orchidis (and the two which 
he reduces to it) to Habenaria, with the remark that, аз а Habenaria, it forms a very 
anomalous member of the section (Platyglossa) where he places it. Believing that this 
plant is really more of an Orchis than of a Лађелагіа, we have ventured to transfer it to 
the former. We are keenly alive to the fact that the line of demarcation between the 
two genera is a very uncertain one; and we think it advisable to give considerable 
weight to the colour of the flower, which in this plant is pink or purple (the prevailing 
colour in Orchis), whereas in the undoubted Indian species of Habenaria the flowers are 
usually of some shade of green or of greenish-yellow, even white itself being uncommon.
