Morphology General Habit
A lofty woody climber.
Morphology Branches
Younger branches ± densely ferrugineous-sericeous, older ones usually glabrous, lenticellate.
Morphology Leaves
Leaf-lamina obovate to oblong-obovate, 4.5–9(–11) × 2–4 cm., obtuse or acuminate, cuneate, with margins somewhat involute, subcoriaceous, glabrous, with 12–16 pairs of lateral nerves, usually eglandular (rarely with a pair of much reduced glands beneath near insertion of petiole); petiole 3–5 mm. long, usually glabrous, canaliculate.
Morphology Reproductive morphology Inflorescences
Inflorescences on leafy branches terminating in racemes, many-flowered, with a robust densely ferrugineous-sericeous rhachis; bracts lanceolate-triangular, 3–4 mm. long, acute, persistent; bracteoles triangular, 1–2 mm. long, eglandular.
Morphology Reproductive morphology Flowers
Flowers 2.5–3 cm. in diameter.
Morphology Reproductive morphology Flowers Calyx
Calyx with (l–)2(–3) circular glands, rarely eglandular; lobes ovate to oblong-ovate, 5–6 mm. long, ferrugineous-sericeous or glabrescent outside, shortly ciliate at margins.
Morphology Reproductive morphology Flowers Corolla
Petals canary yellow, subcircular to broadly obovate, 11–15 mm. long, deeply lacerate at margins or rarely entire, very shortly clawed.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens with oblong-ovate anthers 4.5–5 mm. long; filaments 2–3 mm. long, flattened, enlarged at base, glabrous.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary densely ferrugineous-sericeous; styles 2, ± 12 mm. long, usually glabrous.
Morphology Reproductive morphology Fruits
Wing of samara obliquely oblong to oblong-obovate, 4.5–6 x 1.8–2.25 cm., with upper edge curved towards the acute or subacute apex, clasping the nut to a certain extent but never to its base (see fig. 1/6), usually glabrous.
