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

    Habit
    Medium to large evergreen perennial herbs with thick creeping rhizomes, aerial parts persisting for several years.
    Leaves
    Leaves several, distichous, ensiform, coriaceous, without a midrib.
    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.
    Inflorescences
    Inflorescences composed of terminal rhipidia (umbellate flower clusters enclosed in paired opposed spathes); spathes sheathing, coriaceous, the outer spathe smaller than the inner.
    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.
    Stamens
    Filaments usually free, occasionally united below, anthers linear, appressed to the style branches.
    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.
    Fruits
    Capsules erect or pendent, cartilaginous, irregularly grooved or smooth, tardily dehiscent or indehiscent.
    Seeds
    Seeds irregularly angled, fairly large.
