As treated very broadly, the Liliaceae are mostly perennial herbs from starchy rhizomes, corms, or bulbs comprising about 280 genera and 4,000 species. The leaves are alternate or less often opposite or whorled. The flowers are often showy and are nearly always bisexual and actinomorphic. The perianth typically consists of two whorls of undifferentiated or weakly differentiated petaloid tepals with 3 distinct members in each whorl, or less frequently all of the segments are connate into a common perianth tube or perigynous or epigynous zone that sometimes has an adnate corona. The androecium usually consists of 6 fertile stamens attached to the receptacle or adnate to the perianth tube but rarely 3, 4, or up to 12 may be found. The gynoecium typically consists of a single compound pistil of 3 carpels, a single style commonly with 3 stigmas, and a superior or less often inferior ovary with 3 locules, each containing several to numerous axile ovules. Rarely there are 2 or 4 carpels and locules with axile placentation or only a single locule with intruded parietal placentation. The fruit is nearly always a capsule or berry.

All but the first four entries below are now often treated in more homogeneous, segregate families (indicated in parentheses).
