1–3, not clustered on stout primary rhizome, ovoid, 1.5–2.5 × 1–2 cm;

outer coats enclosing 1 or more bulbs, brown or gray, membranous, lacking cellular reticulation or cells arranged in only 2–3 rows distal to roots, ± quadrate, without fibers;

inner coats white, cells obscure, ± quadrate, or 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, 1–2, basally sheathing, sheaths not extending much above soil surface;
