Leaflets ovate-elliptic to lanceolate, 4-14 by 2.5-7 cm, chartaceous to coriaceous; base cuneate or rounded to subcordate, sometimes subpeltate, in lateral ones sometimes slightly oblique; apex shortly to caudate acuminate; nerves rather inconspicuous, 3-8 pairs, patent or ascending, curved, more or less distinctly looped and joined; veins mainly transverse to the midrib, rather dense; reticulations tessellate. Inflorescences up to c. 15 cm long, shortly and densely tomentose, widely and laxly branched and with rather many flowers. Bracts minute. Sepals ovate, acute, 2-3 by 1.25-1.5 mm, usually distinctly keeled, outside densely pubescent, inside glabrous. Petals lanceolate to linear, 6-10 mm long, blunt, on both sides rather densely minutely tomentose, punctate. Stamens 1-1.5 mm connate, either all fertile or the epipetalous ones sterile, all filaments with few scattered glandular hairs. Fruits obliquely (sometimes even rather strongly curved) spindle-shaped to oblique-ellipsoid, in the latter case usually distinctly shortly stipitate., c. 3-5 by 1-2 cm, bright-yellow to orange, beak usually acute, apical, pericarp thin, coriaceous, outside rather smooth, minutely lengthwise striate, inside densely pubescent.
