Afroptera pilosa has been recorded from the Northern and Western Cape Provinces (Fig. 156). In the former province, it is confined to the Bushmanland Bioregion in the Nama Karoo Biome where the habitat comprises salty, mud-stone soils and receives predominantly late summer / early autumn rains with an average of 100–200 mm per year. Dwarf succulent and spiny shrubs are dominant. While in the latter province, the distribution is in the Rainshadow Valley Karoo, Lower Karoo and Renosterveld Bioregions of the Succulent Karoo, Nama Karoo and Fynbos Biomes, respectively. Two populations have been reported from the Rainshadow Valley Karoo; one seems to be associated with the Koedoesberge-Moordenaars Karoo vegetation type (see description of the vegetation type under distribution of A. obtusa). Another population has been recorded from Prince Albert Succulent Karoo vegetation unit to the west of Prince Albert (see description of the unit under distribution of N. remifera). In the Lower Karoo Bioregion the species has been found in association with Gamka Karoo vegetation type (see description of the vegetation type under distribution of A. exigua). In the Renosterveld Bioregion the vegetation cover is mostly comprises Montagu Shale Renosterveld type and includes Acacia karoo, succulent shrubs. |
