Leaves opposite, narrowly ovate, tapering to an acuminate tip; short tapered petioles are winged. Leaves usually have a pair of small leaflets where the petiole meets the stem. Leaf margins sharply toothed. Inflorescences terminate longish white stalks and form loose clusters (cymes) of small white flowers, very short-tubular and with 5 recurved petals. | |
