Occurs from Nigeria and Ethiopia through to the Western Cape in South Africa. Of the 40 species, 35 are found in southern Africa. The greatest diversity is in the semi-arid habitats of the Northern Cape (Namaqualand and western karoo).

Flowers of Lapereirousia vary greatly in morphology according to the insects that pollinate them (Goldblatt & Manning 2000):

Short-tubed species are pollinated by bees, bombyliid flies, noctuid moths and butterflies.
Long-tubed species with red, purple to pink to cream flowers are pollinated by long-tongued flies in the genera Philoliche (Tabanidae), Prosoeca and Moegistorhynchus (Nemestrinidae).
Long-tubed, pale-coloured, fragrant species are pollinated by sphingid and other moths.
