Lithops karasmontana occurs only in Namibia and is a very variable species with 3 subspecies, one of them with 4 varieties.
Var. karasmontana is found to the west and southwest of the Great Karasberg and on its own supplies most of the variability in the species, ranging from opaque and uniformly coloured plants to ones with narrow channels and markings and others with more or less translucent open windows. All this combined with a great variation in colours, from bluish-white to yellowish brown and brick red.
The flowers are white and usually 2.5-3.5 cm in diameter.
The plants figuring here, were photographed on a rose quartz outcrop near Grunau.
