Leaves in whorls of 3, spreading to porrect, fleshy, flat above, convex beneath, linear or narrowly ellipsoid, 1– 5 mm long, 0.5– 1.3 mm wide, glabrous or margins ciliolate with dendritic hairs to 0.2 mm long, apex acute or subobtuse, sulcate abaxially; petiole pale, 0.3– 1 mm long, with ciliolate margins. Flowers in fascicles or umbels of 2– 8 at branch ends, nodding (?always); pedicel mauve to pink, 1– 7 mm long, glabrous or puberulous with minute simple or larger dendritic hairs; bract in various positions, sometimes leaf-like and at base of pedicel; bracteoles often opposite near middle of pedicel, narrowly obovate, 1.2– 3 mm long, 0.4– 0.8 mm wide, concave, denticulate or ciliolate, sometimes reduced or missing. Sepals pink, free almost to base, 4, subequal, submembranaceous, ovate, narrowly ovate to elliptic, 1– 3 mm long, 0.8– 1.2 mm wide, keeled abaxially, margins with dendritic hairs or minutely ciliolate, apex acute or obtuse.
