Tree to 6-7 m high; d.b.h. to 5 cm; bark smooth, blue-grey; young branches green, smooth, glabrous, with a grey-bluish wax cover on the dried material; old branches dark grey to brown, striate, glabrous. Petioles 4-5(-7) mm long, 1-1.5 mm in diameter, glabrous, lamina inserted on side, broadly grooved adaxially, with grey wax layer. Leaf lamina 7-13 cm long, 3.5-6 cm wide, length:width ratio 1.8-2(3), obovate or rarely narrowly obovate, base rounded to acute, apex acuminate, acumen ca. 10 mm, coriaceous, glabrous, dark green glossy above, flaccid polish green below; midrib but sunken towards the base afaxially, glabrous on both sides; secondary veins 8-11 pairs, uniformally curving upwards, glabrous. Inflorescences erect above foliage, 2-3-flowered rhipidia, leaf-opposed or supra axillary, born during the leaf flush. Flowering pedicels 10-30 mm long, glabrous, with grey wax layer. Upper bract inserted around the center tor sub-apically on the pedicel, 25-30 mm long, ca. 15 mm wide, length:width ratio 1.5-2, ovate, base decurrent, apex slightly acuminate, glabrous, light green with red steaks towards base; margins undulate, glabrous. Sepals 6-10 mm long, 3-5 mm long, length:width ratio 1.5-2, ovate, base truncate, apex rounded to acute, glabrous, green-grey with red steaks towards base; strongly curved upwards, falling when in fruit, margins undulate, glabrous. Outer petals 11-25 mm long, 5-12 mm wide, length:width ratio 1.8-2.5, ovate to narrowly ovate, base truncate, apex acute to rounded, glabrous, yellow streaked with red; hanging down when immature to spreading upwards at anthesis, margins undulate, glabrous. Inner petals 5-8 mm long, 6-13 mm wide, length:width ratio 0.5-1.1, clawed, cordate, base cordate, apex acuminate to obtuse, inside very densely covered with ca. 2 mm long straight hairs, glabrous outside, light yellow striped with purple and red, lamina connivent at margins over receptacle, margins non undulate, densely covered with short curly hairs; claw 3-5 mm long, 2-3 mm wide, claw:inner petal ratio 0.6-0.7, glabrous, bright yellow. Receptacle 4-5 mm in diameter, slightly convex. Stamens in 6-8 rows, ca. 0.7 mm long; connective shield ca. 0.2 long, densely covered with short erect hairs, yellow whitish, those of innermost row slightly appressed against ovary wall. Ovary 0.8-1 mm long, ca. 0.8 mm wide; stigma 1-1.5 mm in diameter, glabrous to sparsely covered with short erect hairs. Fruiting pedicels 6-7 cm long, 2-3 mm in diameter, glabrous. Fruits 25-35 mm long, 15-20 mm in diameter, length:width ratio 1.7-2, ellipsoid to ovoid, apiculate, apicule 3-4 mm long, smooth, glabrous, pale green with white dots, covered in places with grey wax layer; pericarp 1-2 mm thick. Seeds 10-13 mm long, 8-10 mm wide, transversely to flat ellipsoid, no apparent pulp on dried material; testa smooth, dark brown; raphe thickened, rugose, very dark brown; hilum 4-5 mm long, ca. 2 mm wide, narrowly elliptical.
