Shrubs, to 2 m (in cultivation). Young branches densely pubescent. Leaf laminas coriaceous, (elliptic-)lanceolate or rarely ovate-lanceolate, 6-22 by 2.5-8 cm, base rounded to slightly cordate, apex acute to acuminate, glossy, glabrous (except midrib pubescent) adaxially, moderately to sparsely pubescent abaxially, secondary veins 6-14 pairs per leaf, with domatia; petioles 3-8 mm long, moderately pubescent. Inflorescence rachides simple, with rachis internodes remaining short, 1-3 mm long, 2-3-flowered, densely pubescent; pedicels 8-17 mm long. Sepals united at base, broadly ovate, not imbricate, 4-5.5 by 4-5.5 mm, densely pubescent ab- and adaxially. Outer petals creamy white to yellow, ovate, 12-17 by 9-12 mm, reflexing when mature, not clawed, margin not undulate, apex obtuse, densely pubescent ab- and adaxially. Inner petals greenish-yellow with purple spot towards apex, 10-12 by 5-6 mm, claw incurved, densely pubescent abaxially, densely hairy with long hairs towards apex adaxially, with inwardly folded marginal protrusions at the midpoint adaxially. Stamens 0.8-1.3 mm long, connective truncate, glabrous. Carpels 12-20 per flower, 1.6-2 mm long; ovary ellipsoid to oblong-ellipsoid, 1.3-1.5 mm long, moderately hairy; stigma globose, 0.3-0.5 mm long, hairy; ovules 6-10 per carpel. Fruits with up to 16 monocarps, borne on a pedicel 15-25 mm long, 4-6 mm wide, densely pubescent. Monocarps yellow when ripe, (ellipsoid-)ovoid to subglobose, 13-20 by 10-16 mm, smooth, without longitudinal ridge, densely pubescent; stipes 15-22 mm long, densely pubescent. Seeds 2-6 per monocarp, semi-lenticular (lowermost and uppermost within monocarp) or discoid (others), 5-10 by 5-6 mm, glabrous, pitted.
