Braunsia geminata is a rigid, low-growing to mat-forming leaf succulent that grows spreading, woody branches to 20 cm in height. The plant roots at stem nodes.
The short-stalked flowers grow solitary. They have five fleshy, leaf-like sepals and a couple of rings of pink to about white petals spreading around the flower centre to about 4 cm in diameter. A cylindrical bunch of white-filamented stamens and staminodes is erect in the flower centre, the stamens yellow-tipped. The nectar glands form a toothed ring in the base of the flower.
Flowering happens late in autumn and through winter.
The woody fruit capsule has five locules.
The species distribution is in the Western Cape from Ceres to the west of the Little Karoo and the south of the Great Karoo near Prince Albert.
The habitat is rocky and shale succulent Karoo and fynbos flats and slopes where the plants grow in the open in clay and loam soils. The species is not considered to be threatened in its habitat early in the twenty first century (Vlok and Schutte-Vlok, 2015; Smith et al, 1998; Bond and Goldblatt, 1984; iNaturalist; http://redlist.sanbi.org).
