The leaves are narrowed below, linear, lance-shaped, with margin rolled back, the radical leaves narrow, linear to oblong, elliptic, the stalks without wings as long as or shorter than the leaves, which are more or less acute, bluish-green. The few upper leaves have shorter stalks. The flowers are white or pink, in a slender, loose, blunt, terminal spike-like raceme, bulbiferous below, with red bulbs. The fruit rarely matures. The face of the nut is egg-shaped, shining, smooth, lance-shaped. The plant is 4-8 in. high, flowering from June to August, and is a herbaceous perennial.

The veins radiate from the end of the leaf-stalk. The stem-leaves are solitary. The panicle is a spike-like raceme, slender, leafless, loose, the ultimate flower-stalks slender, jointed in the middle, thickened above. The outer perianth-segments are spreading or bent-back, the inner spoon-shaped, with 3-5 nerves. The fruit has a round to heart-shaped wing, and is membranous, veined, notched at the end.
