Euphorbia hallii

A small, rarely documented succulent Euphorbia from the Northern Cape of South Africa, with no georeferenced wild records in GBIF. The one measured site points to the hot, dry interior near Prieska, so grow it like other dwarf Karoo euphorbias: full sun, very sharp drainage and a dry, cool winter.
