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

usually solitary, not clustered on stout, primary rhizome, ovoid, 0.8–1.6 × 0.6–1.4 cm;

outer coats enclosing single bulb, brownish, membranous, with ± obscure reticulations, cells isodiametric to transversely elongate, often contorted, without fibers;

inner coats white to pink, cells obscure, quadrate.

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 dedicuous with scape, green at anthesis, 2, basally sheathing, sheaths not extended much above soil surface;
