It may appear to some Botanists that this is but a slight 

 distinction upon wliicli to found a genus. But it 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 Bonatea, 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.
