Description
PDF

The Liliaceae are mostly perennial herbs from bulbs, comprising about 13 genera and 400 species. The leaves are alternate or whorled, simple, parallel-veined; stipules absent. The flowers are bisexual, actinomorphic or weakly zygomorphic, often showy. The perianth typically consists of two whorls of undifferentiated or weakly differentiated petaloid tepals with 3 distinct members in each whorl. The androecium usually consists of 6 fertile stamens with distinct filaments. The gynoecium typically consists of a single compound pistil of 3 carpels, a single style commonly with 3 stigmas, and a superior ovary with 3 locules, each containing numerous axile ovules. The fruit is a loculicidal capsule or sometimes a berry.  Seeds usually flat and disk-shaped; seed coat not black.
