Descriptions

Iridaceae, Peter Goldblatt. Flora of Tropical East Africa. 1996

Morphology General Habit
Perennials with globose corms with fibrous tunics
Morphology Leaves
Leaves several-many, the lower 2 entirely sheathing (cataphylls); foliage leaves mostly basal, or the upper cauline, blades mostly plane (in South Africa sometimes terete or the margins broadly winged)
Morphology Reproductive morphology Inflorescences
Inflorescence an erect or inclined spike; bracts membranous to scarious, the outer often 3-dentate and the inner 3-dentate and shorter to ± as long as the outer
Morphology Reproductive morphology Flowers
Flowers often orange, or yellow, pink or purple, actinomorphic or zygomorphic, then with stamens unilateral and arcuate; tube short to long; tepals subequal or bilabiate then often the lower 3 each with an adaxial, tooth-like median callus
Morphology Reproductive morphology Flowers Gynoecium Style
Style 3-branched, the branches filiform, somewhat broadened above
Morphology Reproductive morphology Fruits
Capsules globose to ellipsoid
Morphology Reproductive morphology Seeds
Seeds numerous per locule, angular to globose.

Morphology General Habit
Perennial herbs with globose corms, aerial parts dying back annually; corms with fibrous tunics.
Morphology Leaves
Leaves several to many, the lower 2 entirely stem sheathing (cataphylls); foliage leaves mostly basal, or the upper ones cauline, blades mostly plane (sometimes terete or H-shaped in section outside the Flora Zambesiaca area).
Morphology Reproductive morphology Inflorescences
Inflorescence an erect or inclined spike: floral bracts membranous to scarious, the outer often 3-dentate, the inner 2-dentate and shorter than, or about as long as, the outer.
Morphology Reproductive morphology Flowers
Flowers often orange, or yellow, pink or purple, actinomorphic or zygomorphic; perianth tube short to long, tepals subequal or bilabiate with the lower 3 often each bearing an adaxial tooth-like callus in the midline.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually unilateral and arcuate (symmetrical in one S African spp.).
Morphology Reproductive morphology Flowers Gynoecium Style
Style 3-branched, the branches filiform becoming somewhat broadened above.
Morphology Reproductive morphology Fruits
Capsules globose to ellipsoid, more or less membranous.
Morphology Reproductive morphology Seeds
Seeds numerous per locule, angular to globose.
