Haworthia devriesii is only known from the area north of Prince Albert. The globose greyish flowers are reminiscent of Haworthia pehlemanniae, Haworthia globosiflora and Haworthia nortierii and the plants are probably also related to Haworthia agnis. All these species belong to the same group although there are significant differences in the leaves of the plants.
The leaves of Haworthia devriesii are succulent and their shape is somewhat similar to that of Haworthia nortieri and Haworthia globosiflora. The latter two species are seperated from Haworthia devriesii by 200 km and more, while Haworthia pehlemanniae looks more like H arachnoidea and is found some 110 km to the west of Haworthia devriesii in the vicinity of Laingsburg. H devriesii is a unique find and only known from two localities at this stage. At both of these the plants are comparatively rare.
This species is difficult to find in habitat as the leaf markings and color of the leaves mimic their surroundings. At the type locality the plants grow in very sandy soil, under bushes, but also in the open. When in the open, the plants are occasionally almost completely buried in the sand and only visible when in flower.
The flowering time is in September and October.
The habitat photographs were taken with an old Mavica camera with low resolution.
