[(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.
Key to Iridaceae
Corm depressed, cover fibrous. Inflorescence: spike, branched below or not; flowers generally ± 2-ranked, flower bracts green, leathery. Flower: radial or generally bilateral; perianth funnel- or trumpet-shaped, tube curved, lobes ± equal or unequal, oblong or lanceolate; style branches divided ± to middle, thread-like. Fruit: generally oblong. Seed: generally winged at 1 or both ends.Key to Watsonia
± 50 species: southern Africa. (Sir William Watson, English botanist-physician, 1715–1787) [Goldblatt 1989 Ann Kirstenbosch Bot Gard 17:1–148] Many species cultivated as ornamental.
Stem: 1–1.5 m. Leaf: 3–4, 45–80 cm, < 5 cm wide, margins heavily thickened. Inflorescence: > 30-flowered, generally with many ± erect branches. Flower: perianth 3.5–4.5 cm, lobes 1–1.5 cm, ovate-oblong.
