Bulbous herbs. Leaves radical, biseriate, sessile. Inflorescences umbellate, few-to 1-flowered, with 1 or 2 spathes. Flowers white. Tepals subequal, united at the base into a long and narrow tube. Stamens inserted in the throat, basally connected by a thin membrane (false corona) which is sometimes 1-or 2-toothed between the filaments; anthers dorsiflxed. Ovary with 10 or more biseriate ovules filling each cell; style filiform; stigma entire. Capsules loculicidal, 3-valved. Seeds angular by pressure, black.
Moderately large scapose herbs with tunicated bulbs and rather fleshy basal leaves; inflorescence scapose, umbelliform, involucrate, bearing few to several showy sessile flowers; perianth salverform, with a very narrow tube and six spread-ing narrowly linear lobes; stamens inserted on the margin of a very conspicuous turbinate corona, the free portion of the filaments long and very slender; anthers linear, versatile; ovary inferior, 3-celled; fruit a fairly large, tardily dehiscent capsule.
