patently hispid; stems decumbent from a woody root; ascending branches 6–12 in. long; leaves ovate, 1 1/4 by 1 in. (in Drège's type), up to 2 3/4 by 1 1/2 in. (in form megalantha, C. B. Clarke), sparingly toothed and obscurely angular, or frequently subentire (occasionally much toothed, as the leaf of Atriplex), base rounded, 3–5 digitate basal nerves usually distinct beneath; petiole (even of the lower stem leaves) 0– 1/6 in.; bracteoles 1/2– 2/3 in. long (in form megalantha, 3/4 in. long and upwards), elliptic, not cordate at the base; calyx-teeth about 12, linear, 1/5 in. long; corolla cream-coloured; tube 3/4 in. long; limb 1 in. in diam.; or (in form megalantha) tube 1 1/4 in. long; limb 2 in. (occasionally more) in diam.; anther-cells (usually 6 of the 8) with a strong curved spur at the base, also a tuft of beaded hairs at the base and usually with beaded hairs to the summit; pollen most minutely and sparsely tubercled; style with one lobe far below the other; capsule 1/2– 2/3 in. long, glabrous. null

Notes
Between the original type of this species collected by Drège and the extreme form megalantha, C. B. Clarke, there is a series, among which T. flavohirta, Lindau, is near Drège's type. T. atriplicifolia, Lindau (in Engl. Jahrb. xvii. Beibl. 41, 36, 39), with the anther-cells not spurred at the base is either a new species or a form of T. capensis; in the type example of Drège's atriplicifolia (and in all the material above cited), several anther-cells (usually 6 or 4 in each flower) have at the base a linear curved strong smooth spur with a white hard point. This species is diagnosed here from T. aspera by the ovate (not elliptic-oblong) leaves; the var. β differs from all the other material quite as much as T. aspera does, but having ovate leaves is arranged here.
