[(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
[Annual] per; rhizomes compact.Key to Sisyrinchium
Stem: 1 or tufted, ± flat, winged, nodes well above basal leaves with leaves or not, each with >= 1 flower-branch.
Leaf: bases overlapped, sheathing.
Inflorescence: flowers in umbel-like cymes; bracts 2, equal in length or not, margins translucent.
Flower: perianth red-purple, ± blue, violet, yellow (white), parts mucronate, ± alike, outer generally wider; filaments ± free to ± fused.
Seed: ovoid, smooth or pitted.
100+ species: w hemisphere. (Latin, Greek: pig, snout) Use of treatments prior to ± 2003 often results in misidentification. Sisyrinchium douglasii moved to Olsynium.
Unabridged etymology: (Latin, sus, pig, and Greek, rhynchos, snout, alluding to swine digging the roots of some bulbous plant for food, spoken of by Pliny and Theophrastus (W.J. Hooker, 1830). The reason for applying the name to a genus of New World Iridaceae was apparently arbitrary.)
Unabridged references: [Henderson 1976 Brittonia 28:149–176]
Unabridged note: Use of treatments prior to ± 2003 often results in misidentification due to inconsistent or incorrect use of morphological terms and the fact the taxa look very much alike.
Stem: tufted, < 45 cm, green to glaucous, leaf-bearing nodes 0(1).
Inflorescence: translucent margins of inner bract ± uniformly narrow.
Flower: perianth 8–17(20) mm, generally blue to blue-violet, base yellow, outer parts generally elliptic to narrowly oblanceolate, tips rounded to deep-notched. Highly variable, self- or cross-pollinated. Varieties intergrade; 2 others, in WA, BC. [Online Interchange]
