Victoria I. Sullivan in Flora of North America (vol. 26)
Herbs, perennial, scapose, rhizomatous. Leaves in dense basal rosettes, clasping erect branches; blade narrowly linear to lanceolate, oblanceolate, linear-elliptic, or elliptic, flat, leathery, distal margins fused to form subulate tips. Scape 2-10 dm. Inflorescences racemose. Flowers each subtended by 2 subulate, unequal bracts, short-pedicellate; perianth white, yellow, or golden orange, cylindrical, campanulate, or obovoid, abaxial surfaces rough; tepals 6, connate basally; stamens 6, included; filaments adnate to perianth; anthers oblong-lanceolate, longer than filaments; ovary half inferior with proximal portions of perianth adnate at maturity; style 3-branched at apex. Fruits capsular, 3-locular, beaked. Seeds amber, deeply sulcate, ellipsoid to ovoid, 0.5-0.8 mm, lustrous. Some species of Aletris (e.g., A. lutea and A. obovata) are quickly eliminated unless habitats are occasionally burned or otherwise kept clear of undergrowth.

Vascular plants of NE US and adjacent Canada
Fls perfect; perianth tubular to campanulate, 6-lobed, adnate to the lower part of the ovary; stamens 6; filaments short, inserted at the top of the perianth-tube; anthers linear, introrse; style straight, barely 3-lobed, with minute stigmas; fr a loculicidal capsule enclosed by the persistent, withered perianth; seeds numerous, minute, fusiform; perennial herbs from a short, stout, praemorse rhizome or a mere crown, with a basal rosette of narrow lvs, an erect stem bearing bract-like lvs, and a terminal spike-like raceme; perianth roughened with numerous short, scale-like points, giving it a mealy appearance. 25, N. Amer. and e. Asia.
