Purple/pink to nearly white flowers are spaced out on a spike-like raceme 1 to 3 inches long at the top of the stem. Flowers are ¼ to 3/8 inch across with 2 wing-like sepals flanking 2 petals rolled into a column in the center, with a fringed crest.
Leaves are to 1 inch long and 1/6 inch wide, toothless, hairless, usually wider at the tip end, tapering to a narrow or blunt point at the tip with no leaf stem. There are usually multiple, unbranched stems emerging from a sturdy taproot. The stems may be erect but often fan out from the center of the clump, each stem leaning over or sprawling along the ground with the tip rising up (decumbent).
This species also has small underground flowers on short underground stems that produce seed asexually (cleistogamous), though a few upper flowers can do this as well.
