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

    Habit
    Perennials with globose corms with membranous to fibrous tunics
    Leaves
    Leaves few, the lower 2-3 sheathing the base (cataphylls) and membranous, foliage leaves synanthous and 2-4, ± plicate or folded, usually with at least 2 major veins and lacking a distinct midrib, the lowermost largest, the upper smaller and becoming mostly to entirely sheathing (or leaves of the flowering shoot sheathing and elaminate, then laminate foliage leaves sometimes produced on separate shoots after flowering)
    Stem
    Stem terete, often with several diverging branches
    Inflorescences
    spike with many flowers per axis; bracts firm-textured, short, dry only apically or becoming dry and rust-coloured entirely, the outer acute, the inner bilobed, slightly shorter to slightly longer than the inner
    Flowers
    Flowers zygomorphic, relatively small; tepals united in a short tube, unequal, linear-spathulate, obtuse, the dorsal much exceeding the others, arched over the stamens, the lower 3 smallest and channelled
    Stamens
    Stamens unilateral and arcuate
    Style
    Style arching over the stamens, undivided, stigmatic apically
    Fruits
    Capsule globose-trigonous (but often only 1 or 2 locules developed)
    Seeds
    Seeds globose to ellipsoid, glossy, with an obscurely reticulate surface, 1, rarely 2, per locule.
