Morphology and biology.

Perennial geophyte. Bulbous plant. Bulbs are conically cylindrical, 1-1.5 cm in diameter, clothed in grayish, fulvous, fine-meshed, fibrous coat. One or several bulbs are set on a slanting root. The stem is 30-70 cm tall, one third or half of it covered in leaf sheaths. Leaves, usually 2-3 in number, are smooth, flat, lanceolate or oblong-elliptical, with a well-expressed lamina converging into a petiole, 10-20 cm long and 2-8 cm wide, transformed at the base into a 3-7-cm-long leafstalk. The umbel is globular, dense. The spathe is slightly shorter than the umbel, residuary. Pedicels are of equal length, yet are 2-3 times longer than the perianth. Tepals are yellowish white, elliptical, obtuse. Stamina are almost 1.5 times longer than the tepals. The capsule is three-seeded. Seeds are roundish. Autochore. Blossoms in June; bears fruit in July or early August. 2n=16.
