Stem generally underground
Leaves generally basal, often withering early, alternate, generally ± linear
Inflorescence various, generally bracted
Flower generally bisexual, generally radial; perianth often showy, segments generally 6 in two petal-like whorls (outer sometimes sepal-like), free or fused at base; stamens 6 (or 3 + generally 3 ± petal-like staminodes), filaments sometimes attached to perianth or fused into a tube or crown; ovary superior or inferior, chambers 3, placentas generally axile, style generally 1, stigmas generally 3
