Herbs, perennial, scapose, glabrous, from rootstocks; rootstock vertical, 1–12 cm, fleshy, sometimes bulbose; principal roots contractile, arising from tops of rootstocks. Bulbs, when present, ovoid or elongate, scales lunate. Leaves 2–7, basal; blade flat to nearly terete, sometimes keeled. Inflorescences racemose or 1–3(–6)-branched, bracteate, flowers initially crowded, internodes elongating after anthesis. Flowers soon deciduous if unfertilized; tepals persistent, withering separately to base, distinct, yellow or white, each 3–7-veined, equal, 2–6 mm; stamens 6; filaments equal, shorter than tepals, 1–2 mm, inner 3 nectariferous at base; anthers introrse; ovary superior, globose, 3-lobed, 3-locular, placentation axile, ovules 2 per locule; style 1; stigma unlobed or slightly 3-lobed; pedicel 6–15(–30 mm). Fruits capsular, dehiscent, flattened or indented at top, prominently 3-lobed. Seeds glossy black, globose, flattened on 1 side, smooth. x = 12.

Discussion
Species 3 (3 in the flora).
Excluded species:
Schoenolirion texanum (scheele).a. gray and oxytria texana (scheele).pollard are names based upon ornithogalum texanum scheele, which is the same as camassia scilloides (rafinesque).cory, and does not belong to schoenolirion
