[(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
Rhizome [bulbs, fleshy roots]. Leaf: 2-ranked in basal fan; cauline 0–few, reduced, often bract-like, without development of distal portion. Inflorescence: ± flat cyme, flowers 1–many. Flower: perianth parts ± clawed; sepals generally wider than petals, spreading or reflexed, occasionally with white area in basal 3/4, this generally with smaller yellow area; petals erect; stamens free [(not)]; ovary inferior, style branches petal-like [(not)], arched over stamens, each with scale-like flap (with stigmas on inner surface) opposite stamen and just below 2-lobed tip (crest), with sepals forming 3, 2-lipped units [(not)]. Fruit: loculicidal capsule, rounded or triangular, chambers 3. Seed: generally compressed, pitted, light to dark brown (red).Key to Iris
± 160 species: generally northern temperate. (Greek: rainbow, from flower colors) [Wilson 2003 Syst Bot 28:39–46] Hybrids between some sympatric species; Iris germanica only sp. in California with bearded sepals.

Rhizome 9–14 mm diam. Stem: generally branched, 25–40 cm. 2–4. Leaf: odor fetid when crushed; basal 25–35 mm wide; cauline 2–4, similar to basal especially near tip. Inflorescence: flowers 2–9; lowest 2 bracts opposite, enclosing perianth tube, outer 6–8 cm, 16–22 mm wide. Flower: perianth pale yellow to brown, red-brown, or green, veined green or red-brown, tube 11–14 mm, constricted near ovary; sepals 3–5 cm, 18–20 mm wide, obovate; petals 3–4 cm, 11–18 mm wide, narrowly obovate; ovary triangular, style branches 22–30 mm, crests 5–8 mm, stigmas 2-lobed. Seed: globular, generally red.
Damp areas in light shade; 300–1400 m. s Sacramento Valley (ranches only), San Francisco Bay Area; Europe, northern Africa, central Asia. Jun–Jul [Online Interchange]
