Perennial herbs (some tropical species woody or even arboreous), with bulbs or rootstocks, scapose or sometimes leafy stems and usually narrow and entire leaves.  Flowers perfect, regular or nearly so.  Perianth 6-parted or 6-lobed, the segments or lobes distinct, or united below into a tube which is adnate to the surface of the ovary (adnate only to the lower part of the ovary in Lophiola).  Stamens 6 in our genera, inserted on the bases of the perianth-segments or in the throat of the perianth opposite the lobes.  Anthers versatile or basifixed, 2-celled, the sacs usually longitudinally dehiscent.  Ovary wholly or partly inferior, usually 3-celled. Style filiform, entire, lobed, or divided into 3 stigmas at the summit.  Ovules usually numerous, rarely only 1 or 2 in each cavity of the ovary, anatropous.  Fruit capsular, rarely fleshy.  Seeds mostly black, the embryo small, enclosed in fleshy endosperm.

About 70 genera and 800 species, principally natives of tropical and warm regions, some in the temperate zones.
