[(Annual), shrub], perennial herb generally from [ bulb], corm, or rhizome.
Stem: generally erect, generally ± round in ×-section.
Leaf: generally basal (few cauline), 2-ranked, ± sword-shaped, blade edge-wise to stem, with midvein or not; bases overlapped, sheathing.
Inflorescence: generally ± terminal; spikes, umbel-like cymes, or flowers 1; flowers in spikes or 1 subtended by 2 subopposite flower bracts; umbel-like cymes enclosed by 2 subopposite, generally large, leaf-like inflorescence bracts, including various flower bracts.
Flower: bisexual ( unisexual), radial, with stamens erect, enclosing style, or bilateral, with stamens, style to 1 side, stamens not enclosing style; perianth radial, parts free or generally fused into tube above ovary, generally petal-like, in 2 series of 3, outer ± like inner (or not, in Iris, parts in that genus called sepals, petals), upper ± like lower or not; stamens 3, attached at base of outer 3 perianth parts or in tube, generally free; ovary inferior [(superior)], [(1)]3-chambered, placentas axile [( parietal)], style 1, branches 3, entire to 2-branched, thread- or petal-like with stigma abaxial, proximal to tip.
Fruit: capsule, loculicidal.
Seed: few to many.
± 65 genera, ± 2050 species: worldwide, especially Africa; many cultivated (e.g., Crocus, Dietes, Freesia, Gladiolus, Iris, Sisyrinchium). [Goldblatt & Manning 2008 The Iris Family: Natural History and Classification. Timber Press] Gladiolus italicus Mill., Gladiolus tristis L. are urban weeds. Sparaxis grandiflora (D. Delaroche) Ker Gawl., Sparaxis tricolor (Schneev.) Ker Gawl. are waifs. —Scientific Editor: Thomas J. Rosatti.
