Small trees, to 4 m (in cultivation). Young branches densely pubescent. Leaf laminas subcoriaceous, (oblong-)lanceolate, 7-15 by 1.5-6 cm, base slightly oblique, broadly cuneate to slightly rounded, apex acute to rarely acuminate, glossy, glabrous adaxially, sparsely pubescent (denser on midrib) abaxially, secondary veins 8-12 pairs per leaf, without domatia; petioles 4-7 mm long, densely pubescent. Inflorescence rachides simple, with rachis internodes remaining short, 3-5 mm long, 2-3-flowered, densely pubescent; pedicels 25-27 mm long. Sepals free, ovate, not imbricate, 8-10 by 10-12 mm, densely pubescent abaxially, glabrous except densely pubescent at margin adaxially. Outer petals greenish-yellow, turning yellow, (broadly) oblanceolate, 40-60 by 22-35 mm, not clawed, margin undulate with age, apex acute, sparsely pubescent ab- and adaxially. Inner petals pale yellow with purple stripes apically, 14-16 by 14.5-15 mm, claw slightly incurved, densely pubescent ab- and adaxially. Stamens 1-1.5 mm long, connective truncate, glabrous. Carpels 15-20 per flower, 2-2.5 mm long; ovary oblong 1.2-1.5 mm long, sparsely pubescent, stigma club-shaped, 0.5-0.8 mm long, hairy; ovules 8-10 per carpel. Fruits with 7-14 monocarps, borne on a pedicel 20-30 mm long, 3-5 mm wide, densely pubescent. Monocarps yellow when ripe, (ellipsoid-)obovoid to ovoid, 15-30 by 10-25 mm, smooth, with longitudinal ridge, densely pubescent; stipes 2.5-8 mm long, densely pubescent. Seeds 1-10 per monocarp, semi-lenticular (lowermost and uppermost within monocarp) or discoid (others), 9-16 by 8-9.5 mm, surface glabrous, pitted.
