Spreading shrub or woody climber.. Young shoots ferrugineously sericeous, older ones somewhat pubescent but usually glabrescent, lenticellate.. Leaf-lamina obovate, obovate-oblong, elliptic or oblanceolate, 11–18(–20) × 2.8–6.5(–8.5) cm., shortly acuminate, rounded or cuneate at base, chartaceous or chartaceous-membranous, usually glabrous but sometimes finely pubescent, with 7–11 lateral nerves, mostly with 1 or 2 glands beneath near insertion of petiole, and often with a pair of smaller ones near the apex at base of apiculum; petiole 4–8 mm. long, robust, canaliculate, finely pubescent or glabrous.. Inflorescences mostly axillary (rarely terminal) racemes, many-flowered; axis very stout, often thickened (sausage-like), very short and very shortly peduncled or often elongate and then with a longer peduncle (up to 2 cm.), ± densely ferrugineous-or rubiginose-sericeous; bracts broadly ovate-triangular or lanceolate-triangular, usually acute, persistent, inserted at base of or some way below pedicel, with a pair of glands above or at the very base; bracteoles very small, sometimes with a single gland at base.. Flowers ± 2.5 cm. in diameter.. Calyx with usually 3 (rarely 5) circular glands; lobes subcircular or ovate to ovate-oblong, 3–3.5 mm. long, glabrous.. Petals golden yellow, subcircular to broadly obovate, 10–12 × 7–9 mm., shortly clawed, deeply lacerate on the margin.. Stamens with oblong anthers 3.5–5 mm. long; filaments cylindrical, 1–2 mm. long, glabrous.. Ovary ± densely sericeous; styles 2, 0.7–1 cm. long.. Wing of samara (see fig. 1/5) obliquely obovate to obovate-oblong, 3.5–4.5(–5.5) × 1.7–2.1 cm., with the upper margin straight or slightly curved towards the apex, very rarely somewhat constricted at the base, distally obliquely truncate, clasping the nut halfway or somewhat nearer to the base.
