Stem rather slender, 1 to 3 feet high. Leaves oval, elliptic or lanceolate, 3 to 10 inches long, two-thirds to 3 inches wide, becoming smaller above, dark green and glossy above. Flowers lilac-purple or rarely white, fragrant, in a dense, many-flowered terminal raceme, 2 to 8 inches long; petals oblong or oblanceolate, toothed on the upper margin; lip threeparted, one-fourth to one-half of an inch broad, the segments fan-shaped and copiously fringed, the fringe of the middle segment shorter than that of the lateral ones; spur somewhat thickened at the tip, about three-fourths of an inch long, and longer than the ovary.

A. Smaller Purple-Fringed Orchis - Blephariglottis psycodes
The Large or Early Purple-fringed Orchis (Blephariglottis grandiflora (Bigelow) Rydberg) has a large, dense raceme of lilac or purplish, fragrant flowers, the lower lip, three-parted, the segments broadly fan-shaped and copiously fringed to about the middle. The flowers average one-third or one-half larger than those of B. psycodes; otherwise they are very similar and this may be only a large-flowered race of that species. Growing in similar situations.
