Bowkeria cymosa, the escarpment shell-flower or Transvaal shell-flower, is a leafy shrub or small tree (SA Tree List No. 672).  It grows in bushveld or montane grassland along the escarpment in eastern Limpopo and Mpumalanga. It grows to 4 m and has conspicuous white flowers in axillary sprays during summer and autumn. The flowers have red or sometimes yellow streaks in the throat inside the corolla. The fruit is a narrowly elliptic capsule tipped with what remains of the spent style of the flower. It splits when ripe and the valves open to release many tiny seeds (Coates Palgrave, 2002; Van Wyk and Van Wyk, 1997).
