This hairy leaf of what is probably an Eriospermum plant was photographed in the Little Karoo. It looks most like Eriospermum pustulatum, but that plant is known in the Northern Cape, which is some distance.
Other possibilities may be E. pubescens (Western Cape) or E. villosum (Northern Cape), both names indicating hairiness, but both of those have only sparse hairs upon their upper leaf surfaces. The E. pubescens leaf has dense white hairs on its (red) lower leaf surface.
E. brevipes of the Eastern Cape coastal region has very short fine hair. E. titanopsoides (near the west coast) has white leaf hairs, but the leaf is wavy. E. erinum (Nieuwoudtville region) has scattered tubercles on its leaf as well as some sparsely distributed hairs.
This is how matters stand until the right answer is found (Bond and Goldblatt, 1984; iSpot; Wikipedia; Pinterest).
