stem leafy, 1-2^ feet high. Raceme of flowers not as broad 

 as in Habenaria psycodes, but more nearly resembling the 

 spike oi Habenaria lacera in form, yet fewer-flowered. Leaves 

 several, as in Habenaria lacera. 



Continental Range — Pownal Swamps, southwestern Ver- 

 mont; 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, T901 (Marcus White and A. LeRoy Andrews) ; Au- 

 gust 10-16, 1903 (Grace G. Niles).
