Unigenes humifusa, sometimes commonly called the ground lobelia, and previously scientifically Lobelia humifusa and L. disperma respectively, is a sprawling annual reaching heights from 5 cm to 30 cm. The genus is monotypic, has only the one species.
The species distribution is in the southwest of the Western Cape, from the Cape Peninsula to around Stellenbosch, Caledon and Hermanus. The photo was taken at the Salt Pan in Vermont.
The habitat is shady places on damp slopes and flats. The habitat population is deemed of least concern early in the twenty first century (Bean and Johns, 2005; Bond and Goldblatt, 1984; iNaturalist; https://redlist.sanbi.org).
