Shrub to 4 m high. Branchlets indumentum of stellate hairs and glandular hairs, the stellate hairs very dense and of two size classes. Stipules at length caducous or ± persistent, very narrowly triangular to narrowly triangular, 1.5–3 mm long, with stellate hairs and glandular hairs. Climax leaves: petiole 25–100 mm long, indumentum can be similar or different to the branchlet indumentum; lamina ovate to broadly ovate, unlobed to moderately 1–3-lobed (lobes longer than wide to shorter than wide), 55–130 mm long, 55–170 mm wide, cordate base, serrate margin, acute to rounded apex, discolourous or concolourous, indumentum ± on the abaxial surface, the vein indumentum more hairy than the interveinal regions, indumentum of dense stellate hairs (one or two size classes) and glandular hairs. Distal leaves on flowering shoots reduced in size and  shape, narrowly to broadly elliptic. Foliar nectary 3–10 mm long, at base of lamina (sometimes absent). Flowers solitary in leaf axils or sympodial in few-to several-flowered terminal and/or distal-axillary racemoid axes, not pedunculate; pedicels 7–20 mm long with stellate hairs; epicalyx with stellate hairs, 9–13-segmented, connate at the base, subulate and straight, 5-veined, 0.3–0.5 times the length of the calyx, 5–12 mm long; calyx 16–25 mm long in flower, with very dense yellowish stellate hairs, calyx nectary absent; petals 5–8 mm long, pink; staminal column 16–23 mm long, stamens distributed along the entire length of the column, filaments 1–2 mm long; style exserted 4–10 mm beyond length of staminal column, style branches 2–3 mm long, stigmas capitate, stigmatic hairs 0.5–1 mm long. Capsule ovoid, 27–30 mm long, densely hairy with short, straight, unappressed, straw-or rust-coloured hairs, capsule beak 0.5–1 mm long. Seeds angular-subreniform, c. 4 mm long, with striate and pectinate scales.
