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

2–10+, forming threadlike rhizomes, rhizomes 3–10 cm, terminated by bulbels and/or 1–2 basal bulbels that in turn may produce threadlike rhizomes, ± globose, 1–1.5 × 1–1.5 cm;

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

inner coats light yellow, turning reddish on drying, 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.
