=Flowers= white, to rose-purple. =Labellum= about ⅓-½ inch broad, divisions deeply cleft as in _Habenaria lacera_, yet more numerous. =Sepals= round-oval, obtuse. =Petals= cuneate-spatulate and denticulate above. Arms of column slightly acute, similar to _Habenaria psycodes_. =Pollen= stalked, greenish-yellow, somewhat 2-lobed, not obstructing the orifice of nectary, as observed in _Habenaria lacera_. =Spur= longer than ovary, clavate, much enlarged below. =Ovary= intermediate or rather short. =Stem= leafy, 1-2½ feet high. =Raceme= of flowers not as broad as in _Habenaria psycodes_, but more nearly resembling the spike of _Habenaria lacera_ in form, yet fewer-flowered. =Leaves= several, as in _Habenaria lacera_. _Continental Range_—Pownal Swamps, southwestern Vermont; no other station appears to be reported for this natural hybrid of the Purple-Fringed and Ragged Orchises (_H. psycodes_ and _H. lacera_), yet it appears to be flourishing and increasing in numbers in its special haunts. _New England Range_—Vermont, rare; Pownal Swamps August 5, 1901 (Marcus White and A. LeRoy Andrews); August 10-16, 1903 (Grace G. Niles).

Small bogland or woodland orchids, with fibrous creeping roots. =Anther=, 1. =Labellum= erect from base of the column, spurless. =Sepals= and =petals= free. =Anther= terminal, stalked, attached to back of column. =Pollinia=, 2, 1 in each anther-sac, powdery-granular, without caudicle. =Flowers= solitary or 1-3 in terminal raceme. =Leaves= 1-5, alternating, or in whorls as in _Pogonia verticillata_. Seedlings numerous in many places. _Continental Range_—There are about forty-five species of this genus distributed in the wooded regions of the world. The species of _Pogonia_ have formerly been confused with _Arethusa_.
