Corpuscularia lehmannii is a compact succulent with grey, fat but angular leaves, should give quite showy yellow-translucent flowers without too much of a struggle. In the wild, it grows on outcrops in karroid vegetation, also in crevices of rocks.
Delosperma lehmannii is a densely leafy perennial plant forming cushion with a tap-root and some additional adventitious roots on sprawling, prostrate stems. All parts hairless. It has two kinds of shoots: long, ascending flower-bearing shoots with visible internodes and later numerous decumbent short shoots. The leaves are two-edged, 3-angled. Leaves on long shoots are to 4 cm long (mostly 20-25 mm long) and 8-10 mm broad and distant, keel oblique at first, tapping evenly towards the acute apex from above, more abruptly so from the side, each leaf with a developed 2-leaved short shoot in its axil, glaucous, not papillose. On short shoots, the leaves are ovate to almost globose and nearly imbricate, 12-16 mm long, 6-8 mm broad and thick.
