Iridaceae, P. Goldblatt. Flora Zambesiaca 12:4. 1993

Morphology General Habit
Medium to large evergreen perennial herbs with thick creeping rhizomes, aerial parts persisting for several years.
Morphology Leaves
Leaves several, distichous, ensiform, coriaceous, without a midrib.
Morphology Stem
Stem usually erect, bearing leaves at lower nodes, with sheathing leaves at the upper nodes; branching irregularly in the upper half, or forming a divaricately branched panicle.
Morphology Reproductive morphology Inflorescences
Inflorescences composed of terminal rhipidia (umbellate flower clusters enclosed in paired opposed spathes); spathes sheathing, coriaceous, the outer spathe smaller than the inner.
Morphology Reproductive morphology Flowers
Flowers several per rhipidium, pedicellate, borne serially, actinomorphic, Iris-like; pedicels pubescent above; tepals free, all broadly unguiculate, the limbs spreading, outer tepal claws pubescent.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments usually free, occasionally united below, anthers linear, appressed to the style branches.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Style dividing from near the base into 3 broad petaloid branches opposed to the outer tepals, each branch terminating in a pair of erect petaloid appendages (crests); stigmas transverse, abaxial, below the base of the crests.
Morphology Reproductive morphology Fruits
Capsules erect or pendent, cartilaginous, irregularly grooved or smooth, tardily dehiscent or indehiscent.
Morphology Reproductive morphology Seeds
Seeds irregularly angled, fairly large.
