Naming

''S. inaequidens'' exists as a diploid genotype and a tetraploid cytotype.
Initially the diploid ''S. madagascarensis'' and ''S. harveianus'' were assumed to be different species; however molecular analysis showed that they only differ in cytotype.

Distribution

It is native to Southern Africa, including Lesotho, South Africa, Eswatini, Namibia, Mozambique and Botswana.

Habitat

In its native habitat ''S.inaequidens'' occurs at elevations from sea level to 2850 m in a wide range of naturally or anthropogenically disturbed habitats such as river banks, rocky slopes, heavily grazed or recently burned grasslands, and road verges.
