Argyroderma schlechteri Schwantes
Schlecht's argyroderma
Argyroderma schlechteri is a mesemb of the family Aizoaceae endemic to the quartz fields of Namaqualand, South Africa. It was described by Schwantes and named after the Schlecht farm, on whose lands it was originally collected. Its bilobed, stone-like body and flowers emerging between the leaves identify it as a typical member of the genus Argyroderma.

"A. schlechteri is of particular historical interest as it was originally collected on the Schlecht farm, a topographic detail preserved in its specific epithet. Its scant representation in ex-situ collections means that cultivated specimens have conservation value."
