Huernia zebrina subs. insigniflora (Huernia confusa) is a remarkable perennial succulents species with dull greyish-green, 4-angled stems tinged with pink, with acute, spreading teeth. It forms small dense clumps up to 10 cm in diameter. The wide-opening, star-shaped flowers have a distinct, liver-coloured raised ring or annulus at the centre, which looks exactly like a life-belt, and ivory to pink spreading lobes. The corolla lobes are unmarked or, sometimes, faintly mottled or barred and shortly pubescent. Its stems differ from the related Huernia zebrina in being greyish-green with smaller teeth on the angles. Only some authors consider Huernia insigniflora to be a good species on its own; the others classify it as a subspecies of Huernia zebrina
