It differs from the closely related Allium obliquum by purple perianth (not yellow), falcate leaves (not oblique), hemispherical and lax inflorescence, rounded bulbs (not oblong ovate) with coriaceous tunics. It differs from A. carolinianum by inner filaments with obtuse teeth at the base (not triangular without teeth), and rounded (not ovoid), bulbs with dirty yellow coriaceous (not brown, leathery) tunics.

Stem 15–25 cm tall, cylindrical, glabrous, erect, covered by leaf sheaths for 1/5–1/3 of total length. Leaves shorter than scape (2)3–4(5), linear, flat, falcate; leaf blade 12–15 cm long, 10–11 mm wide in the lower part, gradually narrowing to the tip. Spathe persistent, shorter than pedicels, with 1 valve and 2 acute lobes. Inflorescence lax, many flowered, 40–45 mm across, hemispherical, pedicels sub-equal, 9–12 mm long. Perianth campanulate, segments purple, long elliptical, rounded at the apex, 6.5–8 mm long, midrib purple. Stamens for 1/3 longer than tepals (9–11 mm), inner filaments with obtuse teeth at the base; anthers dark purple, oblong, 1.5–2 mm long. Ovary ovoid, with concave nectaries covered by hood like projection at base, white, densely roughish above, style white-purple, exserted, 7 mm long. Seeds and fruits not seen. 2n = 16.
