Root perennial. Stem about twelve inches high, terete, glabrous, gene- 

 rally bearing two leaves and one terminal flower. Leaves alternate, one 

 near the middle, the other at the summit of the stem, lanceolate, acute, 

 nerved, sessile, and semiamplexicaule. Perianth five leaved, purple, ap- 

 proaching to rose colour. Petals distinct, nearly of equal length, somewhat 

 connivent, oblong, the uppermost widest. Labellum scarcely longer than 

 the petals, winged, the centre thickened with elevated crested ridges. Co- 

 lumn much shorter than the lip, thick, solid. Anthers operculate, contained 



in a small depression at the summit. . 



I have specimens with the leaves narrow lanceolate, very acute; and 

 leaves oval-lanceolate, scarcely acute, with the stem shorter and flowers 

 larger. The first from the low country of Carolina and Georgia, the se- 

 cond from the upper districts. 



Grows in damp soils. 



Flowers April — May.
