1–5, not clustered on stout primary rhizome, ovoid, 1.5–2 × 1.2–2 cm;

outer coats enclosing 1 or more bulbs, brown to yellow-brown, membranous, ± prominently cellular-reticulate, cells in regular vertical rows, narrowly rectangular, transversely elongate, without fibers;

inner coats white, cells obscure, transversely elongate.

usually solitary, forming rhizomes;

rhizomes 1–2, terminated by 1–3 new bulbs, short, slender;

parent bulb disappearing by anthesis except for still-functional roots and bulb coats, not basally clustered, oblique-ovoid, 1–1.5 × 0.9–1.5 cm;

outer coats not enclosing bulbs, pale brown, prominently cellular-reticulate, membranous, cells polygonal to oblong, walls thick, obscurely sinuous, without fibers;

inner coats white, cells ± transversely elongate, intricately contorted.

usually deciduous with scape, withering from tip at anthesis, 2, basally sheathing, sheaths not extending much above soil surface;

blade solid, flat, falcate, 7–26 cm × 4–6 mm, margins entire.
