Endemic to South Africa and eastern Botswana, it is common on rocky outcrops, dip slopes and bushveld, and armed with slender spines of about 25mm long. Leaves are alternate or densely clustered in tufts, elliptic to almost linear, margins irregularly and finely serrate, apex frequently notched.

Edwin Percy Phillips, the South African taxonomist, describes the genus Gymnosporia in his 1926 "Genera of South African Plants" as Sepals 5, sometimes unequal, acute, obtuse, sometimes acuminate, with entire, deeply laciniated or fimbriated margins. Petals oblong to sub-orbicular, with the margins entire ciliated or undulate. Disc deeply 5-lobed, sometimes 5-sided, collar-like or saucer-shaped, with crenate or undulate margins. Ovary 2-4-chambered, with 2 ovules in each chamber; style usually short; stigma 2-4-lobed. Fruit a capsule. Seeds often with an aril.
