The leaves are alternate, simple, parallel-veined, and usually with a closed sheathing base. The flowers are bisexual and actinomorphic or commonly slightly to strongly zygomorphic. The perianth is in two usually differentiated series. The calyx is usually of 3 distinct herbaceous sepals. The corolla is usually of 3 equal or sometimes unequal, distinct, deliquescent petals. The androecium typically comprises 6 distinct stamens but commonly 3 or sometimes more are reduced to staminodes. The gynoecium consists of a single simple pistil of 3 carpels, a single style and a superior ovary containing 3 or occasionally by abortion only 2 locules, each containing 1-few axile ovules.
