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

    Habit
    Perennials with small corms with woody to coriaceous tunics
    Leaves
    Leaves few-several, the lower 2-3 membranous and entirely sheathing (cataphylls), foliage leaves lanceolate to linear (rarely terete), the blades plane or sometimes with raised margins and midrib
    Stem
    Stem simple or occasionally branched
    Inflorescences
    Inflorescence a spike; bracts green or membranous to dry apically, the inner smaller than the outer and bicarinate
    Flowers
    Flowers actinomorphic, hypocrateriform (zygomorphic in one South African SPECIES), usually white or pink and frequently closed in the day and opening in the evening; tepals united in a cylindric or curved tube, subequal, spread horizontally or cupped
    Stamens
    Filaments straight, exserted (included in a few South African SPECIES and unilateral in one); anthers facing inwards or articulated on the filaments and horizontal
    Style
    Style usually dividing at the mouth of the tube (or within the tube in a few South African SPECIES), the branches long and spreading, stigmatic along the entire length
    Fruits
    Capsules broadly ovoid to cylindric, sometimes dehiscing only in the upper third
    Seeds
    Seeds many, subglobose to angular, sometimes lightly winged on the angles.
