Procumbent shrub, sometimes almost prostrate, much branched. Branches leafy, pubescent. Leaves 3-nate, 3-6 mm long, erect-spreading, usually shorter than the internodes, linear-subterete, sulcate, hirsute or glabrous, mostly with a tuft of white hairs at the apex. Flowers terminal, 3-nate or in clusters of 3-6; peduncles about 2 mm long, pubescent, slender; bracts approximate, small. Sepals 2 mm long, linear-subulate or narrow-lanceolate, acute, foliaccous, hirsute, shordy gland-ciliate. Corolla 2-5 mm long, suburceolate, tubular-urceolate or ovoid-urceolate, more or less contracted at the throat; usually tetragonous, viscid, glabrous, purple; lobes from the length of the tube, more or less spreading, semiovate, obtuse. Stamens usually 8, occasionally 4-7; filaments narrow, a little dilated, dark-coloured at the apex; anthers exserted or subexserted, 2/3-4/5 mm long, lateral or, rarely, subterminal, narrow-oblong, muticous; pore the length of the cell. Ovary globose, glabrous; style exserted; stigma subsimple.
