Leaf-lamina obovate, oblong-obovate or rarely elliptic, (9-)12-20(-24) x 5-7 cm., abruptly acuminate, rounded or cuneate at the base, membranous, ferrugineous-sericeous on both surfaces when young, very soon glabrescent, only the midrib beneath remaining sericeous, with up to 18 pairs of lateral nerves, usually without glands; petiole robust, 5-7 mm. long, canaliculate, ferrugineously sericeous, glabrescent. Inflorescence loose, forming axillary few- to many-flowered racemes, up to 10 cm. long; axis +/- densely ferrugineous-sericeous; bracts lanceolate, 1.5-2 mm. long, acute, persistent; bracteoles very small, lanceolate, eglandular. Flowers 2.5-3 cm. in diameter. Calyx with 2 or 3 very small circular glands; lobes ovate to subcircular, 3-4 mm. long, somewhat sericeous outside, glabrescent. Petals yellow, obovate to subcircular, 8-12 x 10 mm., distinctly clawed, lacerate at margins. Stamens with lanceolate or oblong anthers 4-5 mm. long; filaments thick, +/- 3 mm. long, glabrous.
