G. carinata var. verrucosa: (limestone in southern coast) Distichous leaves, with dense white tubercles.
This is a highly variable species. Typically it has sharp, triangular leaves, mottled in colour and channeled on their upper surface. The leaves have sharp points at their tips, and usually have keels in mature plants. The tiny spots on the leaves are arranged in bands, giving the leaves faint stripes.
It is proliferous and can form dense clumps.
The natural range of this species is the southern stretch of the Western Cape Province, South Africa. Here it occurs in rocky areas in Renosterveld and Fynbos vegetation, between Hermanus and Mossel Bay.
