Argyroderma braunsii (Schwantes) Schwantes
Braun's Argyroderma
Argyroderma braunsii is a mesemb endemic to the South African Namaqualand, named in honor of succulent plant collector and explorer Georg Braun. It possesses the characteristic bifid body of Argyroderma: two very fleshy leaves fused at the base forming an ovoid to globose body with a grey, smooth surface. It is a winter-growing, summer-dormant species, native to the white quartz fields of the Western Cape.

"A. braunsii was originally described by Schwantes as Mesembryanthemum braunsii and later transferred to the genus Argyroderma. The dedication to Braun reflects the network of collectors and travelers who contributed to the study of Karoo succulents in the early 20th century."
