Crassula alba var. alba green leaves, red stems, and white flowers

In this nearly flat-topped, corymb-like, white inflorescence of Crassula alba var. alba the sturdy, purplish red, branched stems are partly covered in ascending, lance-shaped leaves with wavy margins. The leaves are well-spaced, opposite, also decussate, and decreasing in size on the way up. The leaf margin fringes of tiny short white hairs are just visible in the photo. This stem arises from a basal rosette of bigger leaves, similarly shaped.

The usual colour of Crassula alba var. alba is white in Arabia and the north of Africa, and southwards to at least Kenya. Further south, the flower colour is pink, until it morphs to red in South Africa. But this general trend is not hard and fast, broken by these white flowering plants that grow in colonies of hundreds of grassland plants near Sabie in Mpumalanga (Van Wyk and Malan, 1997; Blundell, 1987; Germishuizen and Fabian, 1982; iNaturalist; iSpot).
