See text Argyroderma is a genus consisting of a dozen species of succulents in the iceplant family from South Africa.

[2] The entire genus is naturally confined to a relatively small region in the far west of South Africa, known locally as the "Knersvlakte" area.

[2] The Cape Floristic Region in South Africa is home to a diverse range of plant life, believed to have evolved through widespread evolutionary radiation.

Within the family Aizoaceae, the genus Argyroderma shows evidence of diversification due to spatially isolated populations experiencing phenotypic divergence from different habitat conditions, leading to genetic differentiation and varying flowering times.

This pattern suggests adaptive radiation in separate populations played a key role in the evolution of the ice-plant family in the diverse landscapes of the southern African winter rainfall deserts.
