The Little Karoo is a narrow tableland in the south, separated from the coastal belt by the Langeberg and Outeniqua mountain ranges. In the north, it is bounded by the Swartberg, of which the mountain range extends from west of Ladismith to the north of Uniondale in the east. The Karoo flats consist of a rich Bokkeveld shale with Cretaceous deposits near Oudtshoorn, and the soil is rich. The area has a summer rainfall, with peaks in March and November, often occurring as soft soaking rain.
Like the Coastal Belt, the Little Karoo is rich in Haworthia and the following species are reported from here: H. angustifolia, H. arachnoidea, H. aristata, H. blackburniae, H. emelyae, H. monticola, H. mucronata, H. retusa, H. setata, H. scabra, H. truncata, H.viscosa, and T. pumila.
