Leaves with petiole of stem-leaves 1.5–3 cm long; lamina of stem-leaves narrowly ovate to ovate, largest ± 9≈3.5 cm, apex acuminate, base unequal-sided, cordate with a sinus to 3 mm deep, margin shallowly crenate-dentate, with finely puberulous midrib above and with domatia in axils of main lateral veins beneath, otherwise glabrous. Inflorescence a 10–30 cm long open much-branched panicle with long spreading branches and flowers in lax dichasial cymes with 3–7 flowers or solitary towards apex; bracts leafy, persistent, green, upwards gradually smaller and narrower; branches and pedicels at base of inflorescence with indumentum as branches, upwards gradually more densely puberulous and with scattered to dense long capitate glands; pedicels to 4 mm long, sharply bent where attached to branch. Calyx puberulous and with long broad glossy many-celled capitate glands (apical 2–3 mm of lobes without glands); lobes linear-lanceolate, 0.5–1 mm wide, ventral and lateral 10–12(–16 in fruit) mm long, dorsal 13–15(–20 in fruit) mm long, 2–3(–5 in fruit) mm longer than the others.
