Petiole 3-5 mm; leaf blade elliptic, 8-13 × 4-5.7 cm, decidedly leathery, abaxially shortly pubescent, adaxially glabrous, midvein adaxially flat or grooved basally or over entire length, secondary veins 5-7 on each side of midvein and abaxially obvious, reticulate veins not obvious, base subcordate, apex obtuse to rounded and mucronulate. Inflorescences at apex on lateral branches forming short racemes, or axillary and terminal on lateral twigs thus forming a panicle, 3-6-flowered; peduncle 2-3 cm, trichomes like those on new twigs. Pedicel 5-7 mm. Sepals 5-6 mm; sepals of outer whorl inwardly concave, outside shortly pubescent, inside glabrous; sepals of inner whorl obovate, ± same size, nearly flat, outside shortly tomentose at middle, inside glabrous.
