Lapeirousia

Description

Lapeirousia is a genus in the plant family Iridaceae. It is endemic to sub-Saharan Africa, about a third of the species occurring in fynbos. Lapeirousia are cormous plants, usually small, and with deciduous leaves. The corms are small, campanulate to triangular in outline, and flat-based. The tunics comprise hard, woody layers, of which the innermost layers are entire. The leaves are basal, often solitary. They may be plane and falcate, or linear and ribbed. Various forms of scape occur; they may be either subterranean or aerial, and simple or branched. The inflorescence is a spike, sometimes contracted and fasciculate or a corymbose panicle. There are firm, green bracts, either small and subequal, or with the outer bract very large, often keeled, crisped and ribbed. The perianth may be either actinomorphic or zygomorphic; the tube short or very long. It might be slender and cylindrical, adapted to pollination by long-tongued flies, or it might be funnel-shaped. The flowers' lobes may be subequal and spreading, or unequal with upper largest petals erect, the lower three forming a lip. The stamens are symmetrically arranged. The fruit is a membranous capsule containing many small seeds, either globose or angled by pressure.
