  • Description

    Description - Tree to 25.0 m tall, the young branches tomentellous becoming glabrescent with age. Leaves trifoliolate; petioles 1.0-5.0 cm long, terete, tomentellous; leaflets shortly petiolulate, the terminal petiolule 5.0-14.0 mm long, the lateral petiolules shorter than the terminal one, the petiolules pilose, canaliculate; the laminas obovate, symmetrical, coriaceous, rounded to mucronate at apex, the mucro not exceeding 3.0 mm long, cuneate at base, crenate at margins, glabrous above except for sparsely puberulous midrib, sparsely tomentellous-pilose beneath especially on midrib and venation, the terminal lamina 6.0-11.0 cm long, 3.0-5.0 cm broad, the lateral laminas smaller than the terminal one; midrib slightly impressed above; primary veins 10-12 pairs, prominulous above, prominent and tomentellous beneath; stipels absent. Stipules oblong ca 1.0 mm long, persistent. Peduncles 2.0-4.5 cm long, terete, tomentellous, not conspicuously lenticellate. Inflorescences elongate racemes, ca 20-35-flowered, the rachis 5.0-9.0 cm long, tomentellous; flowering pedicels 7.0-10.0 mm long, ebracteolate, tomentellous. Calyx broadly cupuliform, 1.5-2.5 mm long, tomentellous on exterior, 5 pointed. Corolla ca 1.0 cm long, the lobes 5, remaining attached at apex to form a calyptra, and circumscissile at base, yellow. Stamens numerous, ca 214, the filaments free almost to base, 5.0-10.0 mm long, yellow, the apical portion tuberculate, the anthers small. Ovary globose-ellipsoid, ca 12-locular, glabrous on exterior. Styles 11-13, ca 1.5 mm long, glabrous. Fruit flattened-globose, ca 1.5 cm broad, 1.0 cm long, not conspicuously ribbed or pointed, 10-12-locular; exocarp glabrous, smooth; pericarp thick, hard, smooth, the interior glabrous.

  • Discussion

    This species is easily recognized in the genus by the pilosity of the petioles, peduncles and inflorescences.

    Collected in flower June to December, and fruit January and February.
