Crassula brevifolia is a succulent plant native to the arid western edge of South Africa (including the Namaqualand, as far south as Vanrhynsdorp) as well as southern Namibia.
Description
A small (reaching 50cm in height), branching, perennial shrub.
It has distinctively short, thickly-succulent leaves, which are roughly triangular in cross-section but with slightly rounded angles (leaf-margins). It has flaking brown bark on its thin, woody stems.
Variation
This is a very variable species, with two subspecies and many regional forms.
- subsp. brevifolia. The type subsp. grows on exposed quartzitic or granite outcrops, from Namibia to as far south as Vanrhynsdorp. It has papillate ovaries (each with 18-24 ovules), and the leaves usually point upwards, between visible internodes.
- subsp. psammophila. A rarer subspecies that favours flatter sands or gravels near the Orange River in the Northern Cape Province.[1]
Related species
This species is closely related to Crassula rupestris and Crassula perforata.[2]
