About Crassula undulata Haw.
Crassula undulata Haw. is a densely branched, bushy perennial that reaches roughly 400 millimeters in height. Its leaves are somewhat fleshy, and are often marked with red speckles. A line of rounded, pearl-like hairs along the leaf margins creates a silvery edge on the leaves. Immature stems have small downward-pointing hairs that give the stems a silvery tinge. The leaves grow in opposite pairs, arranged thickly in regular rows along the stems. This species grows on south or south-west facing slopes, as well as in gorges, on rock outcrops, on ledges, and in rock crevices. It is found in the Riviersonderend Mountains adjacent to Stellenbosch, in the Western Cape province of South Africa, an area that extends northward from the Cederberg mountains. It also occurs in the Fynbos and Succulent Karoo regions.
