Root perennial^ composed of two small tubers. Stem one to two feet 

 high, leafy, glabrous. Leaves lanceolate, acute, entire, nerved, sheathing at 

 base, six to eight inches long, one to two wide. Flowers in a terminal 

 spike, yellow, each protected by a leaf at base. Perianth 6-parted, 3 segments 

 exterior, the upper erect, concave, the two lower obpvate, deflected; three 

 interior, the two lateral very small, incised at the summit; the inferior seg- 

 ment or labellum narrow lanceolate, longer than the lateral segments, beau- 

 tifully laciiiiate or fringed. Horn at the base of the labellum filiform, longer 

 than the germ. Capsule triquetrous, six furrowed, one celled, three valved. 

 Seeds very numerous, v-ery small. 



Grows in wet soils — common along the margin of swamps. v 



Flowers July — August.

This plant at least as understood by many of our botanists, though readily 

 distinguished by its white corolla or perianth, is a very doubtful species. It 

 grows intermingled with the O. Ciliaris, and excepting by colour is not 

 easily discriminated. In the plants I have examined neither labellum nor 

 horn furnished any permanent distinctions. 



Grows with the preceding species in wet soils. 



Flowers July — August.
