 long as the ovary ; flowers medium size. 

 Hob. Moist woods, and thickets : not very common. FL June. Fr. 



Obs. There has been sad confusion in the synonymy of this, and 

 the following species, ever since the days of LINNAEUS ; of which, 

 see an interesting and lucid exposition, by Prof. A. GRAY, in 

 SILLIMAN'S Journal, Vol. 38. p. 306. 



* * Flowers purple ; lobes of the lip broadly cuneate.

 of LINNAEUS appears really to have been his 0. psycodes.

Stem about 2 feet high, rather stout, angular and fistular. Leaves 3 to 6 inches 

 long, broader than the preceding, sessile and sheathing, usually 4 larger ones 

 below, and 2 or 3 small ones above* Spike 3 to 5 or 6 inches long, rather open, or 

 loose, 2 to 2% inches in diameter ; flowers large, pale purple. 

 Hob. Along rivulets, on the slaty hills : rare. Fl. June. Fr. 



Obs. A superb plant, nearly allied to the preceding ; and both, 

 well entitled to a place in flower-gardens.

Pollen pulverulent, of angular loosely cohering granules, forming 4 or 2 maflBcs
