There are 15 Namibian species, all with similar flowers. They are difficult to distinguish, so I can't identify these to species level. The first three were seen in the Orange river valley about 30 km east of Sendelingsdrif, on the C13.
This seems to me to be different, with more glaucus, rounded-oval leaves.
Below is a third species, possibly procumbens?
Below is a another, dwarf, species, seen beside the D707, north of Aus. 7th. August, 2007.
