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

    Habit
    Evergreen perennial herbs with large corms, aerial parts persisting for several years; corms with coarsely fibrous tunics.
    Leaves
    Leaves several, the lower 2–3 sheathing the stem base (cataphylls), these often dry and becoming fibrous; the foliage leaves linear, plane, with many strong parallel fibro-vascular veins, often without a midrib.
    Stem
    Stem terete, slender and wiry, usually branched.
    Inflorescences
    Inflorescence consisting of spikes in a lax panicle; spikes few to many, erect or pendulous, terminal on the main axis and at the ends of wiry lateral branches of the flowering shoot; floral bracts ± solid, or scarious, and often translucent, lacerate above and usually brown-streaked or veined.
    Flowers
    Flowers usually pink (also red, purple, yellow or white in southern Africa), actinomorphic, usually pendent and campanulate, with a fairly short campanulate perianth tube; tepals subequal; stamens, and often the style, included.
    Stamens
    Stamens symmetrically disposed.
    Style
    Style exserted from the perianth tube, seldom exceeding the tepal lobes; style branches simple, short, filiform.
    Fruits
    Capsules globose, coriaceous.
    Seeds
    Seeds globose or lightly angled, hard, smooth and often shiny.
