It may appear to some Botanists that this is but a slight 
distinction upon which to found a genus. Butit is to be 
remembered, firstly, that it is a decided organic difference, 
inasmuch as it is the developement of a new organ in the 
apparatus for reproduction; secondly, that it is a constant 
and obvious character which in many cases is far more 
remarkable than even in the species before us; and more- 
over, that after being limited within the comparatively 
narrow bounds that I have assigned it, and after striking off 
the genera Donatea, Peristylus, Platanthera, Aopla, and 
another or two, the genus Habenaria still comprehends no 
fewer than eighty-five well ascertained species, to which 
many more will doubtless have to be added. 
This plant must have the heat of a damp stove, when in a 
growing state, but will doubtless partake of the habits of its 
kindred species in requiring a long period of coolness and 
dryness, while its roots are at rest, after the leaves have 
perished.
