    Habit
    Shrub or small tree 2–7 (10) m. high, often climbing.
    Branches
    Branches sometimes arching or pendulous, striate and with dense fulvous to orange-brown spreading villous indumentum when young, eventually terete and tomentellous to glabrescent, with whitish-cream spongy striate or grooved bark on the older shoots.
    Leaves
    Leaves variable in shape and indumentum, petiolate; lamina 4·5–13 (17·5) × 1·6–4·3 (4·8) cm., oblong or oblanceolate to obovate (rarely elliptic), acute or shortly acuminate to rounded at the apex, cuneate to truncate or subcordate at the base, subentire to strongly dentate with triangular or ciliate teeth, chartaceous, rusty- or fulvous-pilose along the midrib above and below and on the nerves below, with the other parts varying from densely pubescent to glabrous, often with domatial tufts in the nerve angles below, with midrib and 12–13 nerves impressed above and raised below, and densely reticulate venation less prominent on both sides; petiole 4–8 (11) mm. long, spreading-rusty- to fulvous-pubescent; stipules 4–7 mm. long, pinnatifid with long or short lobes, densely sericeo-pubescent on both sides, deciduous.
    Flowers
    Flowers solitary or rarely paired, in axils of foliage leaves; peduncles 8–26 mm. long, ± slender, ± densely spreading- or appressed- rusty- or fulvous-pubescent (rarely glabrous).
    Calyx
    Sepals 6–8 mm. long, ovate or ovate-lanceolate to elliptic, obtuse to rounded, shallowly vertically ribbed, appressed-rusty- or fulvous-pubescent outside, pubescent near the margin or wholly glabrous within (rarely glabrous on both sides except round the margin).
    Corolla
    Petals yellow, 16–25 mm. long, triangular-obovate, rounded to retuse at the apex, with pubescent margin, otherwise glabrous.
    Stamens
    Stamens with linear glabrous filaments; anthers ovate-oblong, usually with an apical tuft of hairs.
    Pistil
    Ovary c. 2·5 mm. long, ovoid-pyriform, glabrous; styles (2) 3 (4), free, glabrous; stigmas broadly capitate.
    Fruits
    Drupe up to 3 cm. long, obovoid, apiculate, with (2) 3 (4) fertile 1-seeded loculi and thin orange-yellow pericarp.
    Seeds
    Seeds c. 10 mm. long.

    Habit
    Small tree, shrub or climber; trunk with rough greyish bark.
    Twigs
    Young twigs with dense golden or light-brown short spreading pubescence, becoming paler brown or greyish-cream and glabrous with age, either corky and grooved or thin and covered with many raised round lenticels.
    Tendrils
    Hooks opposite or subopposite.
    Leaves
    Leaf-blade elliptic, obovate or broadly oblanceolate, 5–14 cm. long, 2–5.5 cm. broad, acute, mucronate or rounded, entire to serrate, either practically glabrous and chartaceous, or softly and densely pubescent especially on the veins beneath; lateral veins 11-14 pairs, prominent beneath.
    Stipules
    Stipules either digitate-laciniate, 3–5 mm. long, with short connivent or spreading lobes, usually very early deciduous and with golden-brown spreading indumentum, or else pinnatilobed, 5–8 mm. long, may be persistent on first-year twigs, with appressed silvery-grey hairs.
    Flowers
    Flowers usually solitary in leaf-axils; peduncle stiff and slender, 5–25 mm. long; bracts small, shaped as stipules.
    Calyx
    Sepals ovate to elliptic or oblong, 6–9 mm. long, densely pubescent outside, practically glabrous within, greyish or yellowish-green.
    Corolla
    Petals obovate, clawed, somewhat rounded and ciliate at apex, otherwise glabrous, yellow.
