At first sight this genus would seem to be the same as a section of 
Habenaria proposed by Dr. Brown in his Prodromus, p. 312, and cha- 
racterized by having the bases of the anther united lengthwise to the 
column ; and for a long time I so regarded it. But as the bases of the 
anther are, in all undoubted Habenarias, united to the stigmatic canals, 
this character falls to the ground; and the genus has to depend upon 
another distinction, to which I can discover no exception; namely, to the 
absence of the fleshy processes of the lower lip of the stigma. Ode 
Platanthera is the same as Habenaria. The species may be very naturally 
arranged as under.
