This genus differs from Platanthera in having the glands of the yu 
masses concealed by the inflexed points of the stigmatic canals, Ww e 
thus form an imperfect pouch, and in the enlarged projecting pen 
lip of the stigma or rostellum. Gymnadenia Chusua approaches ! d 
structure, but the cells of the anther of that species are parallel an 
contiguous.
