Smicrostigma viride, synonymously known as Erepsia viridis, Mesembryanthemum integrum, Mesembryanthemum viride, Ruschia integra or Ruschia viridis, is a low-growing shrublet of up to 40cm high, with smooth, succulent stems which become woody with age. The hooked triangular leaves (in cross section) are fused into pairs at the base, to sheath the stem below. The purple flowers are 25 mm in diameter and appear singly on the stem tips from September to January. The woody fruit capsules store the small, pear-shaped, brown to black, rough-surfaced seeds in seven to ten chambers. This plant has great horticultural potential and should be introduced as a garden subject. It is drought tolerant, and the plant has a neat appearance with a distinct leaf shape.
