DescriptionThis species can be distinguished by its fleshy, succulent leaves, which are a minimum of 2 mm in thickness. In addition, the leaves are smooth, sessile, egg-shaped (with the narrowest part against the stem), with bright red margins. The leaf normally has a faint line of hair, along its reddish margins (but the hairs tend to fall off at the leaf tip).[1] In its growth form, C.rubricaulis becomes a small (30-50 cm), rounded, branching, perennial shrub, with smooth, red-brown stems ("rubricaulis"="red-stemmed"). The hard, brittle branches root if they lie against the ground. It produces large numbers of white, star-shaped flowers in the middle and late Summer. It is a close relative of the species Crassula dejecta, which also inhabits the mountains of the south western Cape.[2] DistributionThe Red-stem Crassula occurs around the Riviersonderend and Langeberg mountains in the west, in the coastal rocky mountain shrub around Knysna and as far east as Port Elizabeth.[3] References{{commons category}}{{Wikispecies}}1. ^Crassula rubricaulis - PlantzAfrica {{Taxonbar|from=Q15482583}}2. ^{{cite book|author=Doreen Court|title=Succulent Flora of Southern Africa|url=https://books.google.com/books?id=W6ZfOBb-QdsC&pg=PA92 |year=2000|publisher=CRC Press|isbn=978-90-5809-323-3|page=100}} 3. ^Crassula rubricaulis - PlantzAfrica 3 : Crassula|Flora of the Cape Provinces|Plants described in 1753 |
