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 obovate, 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 laciniate 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, very small. 
Grows in wet soils — common along the margin of swamps. 
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.
