Flora of North America species comparison

1–3, larger bulbs each usually with cluster of 10–30 easily detached bulbels to one side of base, not clustered on stout, primary rhizome, globose to ovoid, 1–1.6 × 0.8–1.5 cm;

outer coats enclosing 1 or more bulbs, brownish, membranous, without fibers;

inner coats white to pink;

inner and outer coats frequently without obvious reticulations, these, when present, contorted.

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.

persistent, green at anthesis, 2, basally sheathing, sheaths not extending much above soil surface;

blade solid, flat or channeled, 10–25 cm × 1–4 mm, margins entire.
