Characteristics

Shrubs 1–2 m tall, much branched. Branchlets brownish to grayish brown, terete, with sparse, minute prickles, with dense appressed silvery-gray or yellowish gray silky hairs, glabrescent. Leaves palmately compound, 3–5-foliolate; petiole 2–5 cm, lateral leaflets sessile or subsessile, sericeous; stipules caducous, free, lanceolate or ovate-oblong, 1.2–2 cm, sometimes to 2–3 cm on sterile branchlets, often broad, membranous, abaxially densely sericeous, not divided; blade of leaflets oblong or lanceolate to oblanceolate, 8–12 × 1.5–3.5 cm, pinnately veined with (20–)30–50 pairs of parallel lateral veins terminating at margin, midvein and lateral veins prominent abaxially, impressed adaxially, abaxially densely silvery-gray or yellowish gray appressed-sericeous, adaxially glabrous or long hairy along midvein, base cuneate, margin sharply serrate to doubly serrate, apex acuminate to caudate. Inflorescences terminal and in axils of apical leaves, cymose panicles, ca. 15–20-flowered, sometimes flowers in clusters in leaf axils; rachis and pedicels sericeous or glabrescent; bracts lanceolate or ovate-oblong, smaller than stipules, sericeous. Pedicel 1–2 cm. Flowers ca. 1.5 cm in diam. Calyx abaxially densely silvery-gray or yellowish gray sericeous or glabrescent; sepals ovate-triangular to ovate-lanceolate, 6–12 × 3–7 mm, margin entire, apex acuminate to caudate. Petals white or greenish white, elliptic or obovate, much smaller than sepals, glabrous, base not distinctly clawed. Stamens ca. 50–150, glabrous, somewhat shorter or ca. as long as petals. Pistils ca. 80–100 or more, shorter than stamens; apical part of ovary and basal part of style long hairy. Aggregate fruit orange to red at maturity, semiglobose or globose-ovoid, 7–10 mm in diam., sericeous when young, glabrescent; pyrenes distinctly rugose. Fl. Jul–Aug, fr. Sep–Oct.
More
Shrubs, up to c. 3 m high, sometimes ± climbing and up to 10 m. Stems densely long-hairy, prickles very few or none, up to 3 mm. Leaves pedately 5-foliolate, in the inflorescence sometimes fewer leaflets, young leaflets folded lengthwise, petiole 2-10 cm long. Stipules on the junction of twig and petiole, oblong to lanceolate, 2-4 by 0.5-1 cm, entire, cuspidate, hairy outside, falling early. Leaflets oblong to lanceolate, terminal ones 7-18 by 2-7.5 cm, lateral ones smaller, base acute, margin caudately serrate, apex acuminate to caudate, pergamentaceous, (20-)30-40(-50) pairs of nerves, upper surface variously hairy, lower surface always densely sericeous on main nerves, either short-woolly and also long-sericeous or quite glabrous between the nerves, the indumentum silvery. Inflorescences terminal and lateral thyrsi, up to 5 cm long and with up to 15 flowers. Bracts stipule-like. Pedicels up to 2 cm, densely sericeous. Hypanthium 5-9 mm across, densely sericeous outside. Sepals (ovate-)triangular, 6-13 by 2-7 mm, entire, long-pointed to acuminate, indumentum outside as hypanthium. Petals obovate to ± rhomboid, 4-5 by 2-3.5 mm, early falling, rounded, (greenish) white. Stamens 50-150, filaments up to 4 mm, anthers 0.7-1 mm long. Pistils c. 80 to over 100, ovaries long-hairy in apical part, on elevated, hairy torus, style up to 5 mm long, long-hairy. Collective fruits globose-ovoid, c. 1 cm in diam., sepals upright to slightly spreading. Fruits up to 2.5 by 2 mm (dry), exocarp hairy, orange to red, mesocarp juicy but only a thin layer when dry.
An evergreen shrub. The canes are 3 m long and arch over. Plants develop sucker. The stems are 5-8 cm across. The leaves are large and pleated and divided into five leaflets. The leaves are satiny underneath on top and silvery underneath. The fruit are red.
