Haworthia retusa var. suberecta was previously called H. turgida var. suberecta. It is a stemless leaf succulent bearing its soft, succulent leaves in a basal rosette. The rosette becomes 5 cm to 6 cm in diameter. The plant tends to form clumps from basal stolons.
The variable leaves are truncated and rounded at their tips. Leaf colour is olive-green to brown-red or purplish and mottled or lined whitish. Leaf size is up to 3 cm long by 1,2 cm wide and almost as thick. The inflorescence is wiry, about 20 cm tall bearing about 25 white flowers with dark veins on their segments. Blooming occurs in spring.
The distribution of the variety is in the Western Cape between Swellendam and Riversdale. The habitat is limestone or shale slopes where the plants shelter under adjacent vegetation, mainly fynbos. This variety is deemed to be threatened in its habitat early in the twenty first century (http://llifle.com; www.redlist.sanbi.org).
