Characteristics

Shrub 2–3 m high, with short, spreading branches. Branchlets moderately to very densely hairy with fine and coarse yellow stellate hairs and glandular hairs. Stipules at length caducous, very narrowly triangular to narrowly triangular, lobed or unlobed, 4–14 mm long, with stellate hairs and glandular hairs. Mature leaves: petiole 30–80 mm long, indumentum can be similar or different to the branchlet indumentum; lamina orbicular, deeply 5–9-lobed (lobes longer than wide), 70–150 mm long, 100–180 mm wide, cordate to truncate base, serrate margin, acute or acuminate apex, discolourous or concolourous, the indumentum more dense on the abaxial surface, the vein indumentum more hairy than the interveinal regions, indumentum of moderately dense to very dense stellate hairs (two size classes) and glandular hairs. Distal leaves on flowering shoots reduced in size and shape, narrowly ovate to orbicular. Foliar nectary absent. Flowers solitary in leaf axils or sympodial in few-to several-flowered terminal and/or distal-axillary racemoid axes; pedicels 6–19 mm long with stellate hairs; epicalyx with stellate hairs and bristles (> 3 mm long, straw-coloured and at right angles to the epicalyx), 9–11-segmented, fused at the base, linear or subulate and straight, 0.3–0.75 times the length of the calyx, 5–11 mm long; calyx 16–20 mm long in flower, indumentum like the epicalyx, calyx nectary absent; petals 5–8 mm long, pink; staminal column 13–2  long, stamens distributed along the distal 11–17 mm of the column, filaments c. 1 mm long; style exserted 3–8 mm beyond length of staminal column, style branches 1–2 mm long, stigmas capitate, stigmatic hairs 0.2–0.5 mm long. Capsule broadly ovid, 13–18 mm long, densely hairy with appressed and ascending hairs, capsule beak 0.5–2 mm long. Seeds angular-subreniform, c. 4 mm long, with striate and pectinate scales.
