inner coats white, cells obscure, arranged in vertical rows, forming distinct herringbone pattern or ± quadrate, V-shaped.

1–10+, not clustered on stout primary rhizome, not forming rhizomes, renewal bulbs formed within coats of parent bulb, or borne terminally on rhizomes outside coats of parent bulb, parent bulb disappearing by anthesis except for still-functional roots and shriveled bulb coat, ovoid or oblique, 0.6–2 × 1–2.5 cm;

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