Crassula expansa is a very variable species which is widespread from southern Namibia to Tanzania and Madagascar. There are 4 subspecies, of which ssp. expansa is the most common.
This is a short-lived plant with soft and usually creeping branches, forming mats to 6 cm tall and 50 cm across.
The branches are green to reddish, and rooting at the nodes. Its leaves have a wedge-shaped base and a sharp tip; they are 6-12 mm long and 4-6 mm wide, inversely egg-shaped to almost linear, with a flat upper surface and a convex lower surface, or rarely almost round in cross-section; they are yellowish green to brown (or red when plants flower) with a reddish margin and often shiny.
The small (about 3 mm in diameter) cup-shaped flowers are white, often tinged red and appear mainly in July-December, but also at other times, especially after occasional rains.
Plants are found in KwaZulu Natal and in the Northern, Eastern and Western Cape Provinces, often on rocky or sandy slopes and sometimes abundant in disturbed places.
Thank you for your comment. Pics are from Namaqualand and Little Karoo.
