2–10+, not rhizomatous, ovoid or more elongate, 1–2.5 × 0.8–2 cm;

outer coats enclosing 1 or more bulbs, gray or brown, reticulate, cells rather coarse-meshed, open, fibrous;

inner coats whitish, cells vertically elongate and regular or obscure.

usually solitary, not clustered on stout, primary rhizome, ovoid, 1.5–2.5 × 1–1.5 cm;

outer coats enclosing single bulb, brown or grayish, membranous, lacking cellular reticulation or cells arranged in only 2–3 rows distal to roots, ± quadrate, without fibers;

inner coats white, cells not visible.

persistent, usually green at anthesis, usually 3–5, sheathing less than 1/4 scape;

blade solid, ± straight, flat, channeled, (6–)12–30 cm × 1–3(–5) mm, margins entire or denticulate.

usually deciduous with scape, withering from tip at anthesis, 1, basally sheathing, sheath not extending much above soil surface;

blade solid, flat or broadly channeled, ± falcate, 8–33 cm × 1–10 mm, margins entire.

persistent, solitary, erect, terete or somewhat 2-angled, 10–50 cm × 1–3 mm.

usually forming abcission layer and deciduous with leaves after seeds mature, frequently breaking at this level after pressing, solitary, erect, solid, terete, 2–20 cm × 1–3 mm.

persistent, erect, compact, 10–25-flowered, hemispheric to globose, not producing bulbils, or 0–5-flowered, largely replaced by ovoid, acuminate bulbils;

spathe bracts persistent, 2–3, mostly 1-veined, ovate to lanceolate, ± equal, apex acuminate, beakless.

persistent, erect, compact, 8–20(–30)-flowered, globose to conic, bulbils unknown;

spathe bracts persistent, 3, 9–13-veined, broadly ovate, ± equal, apex abruptly acuminate.

urceolate-campanulate, (4–)6–8(–10) mm;

tepals erect or spreading, pink to white, ovate to lanceolate, ± equal, not withering in fruit and permanently investing fruit, or withering if fruit not produced, midribs papillose, becoming callous-keeled, margins often obscurely toothed, apex obtuse to acuminate;
