A lofty woody climber. Younger branches +/- densely ferrugineous-sericeous, older ones usually glabrous, lenticellate. Leaf-lamina obovate to oblong-obovate, 4.5-9(-11) x 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. 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. Flowers 2.5-3 cm. in diameter. 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. Petals canary yellow, subcircular to broadly obovate, 11-15 mm. long, deeply lacerate at margins or rarely entire, very shortly clawed. Stamens with oblong-ovate anthers 4.5-5 mm. long; filaments 2-3 mm. long, flattened, enlarged at base, glabrous. Ovary densely ferrugineous-sericeous; styles 2, +/- 12 mm. long, usually glabrous. 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. Figs. 1/6, p. 4, 2/1-6, p. 10.
