Leaves subcoriaceous, elliptic to elliptic-oblong, 9-15 by 4-7½ cm, 8-10-nerved; slightly acuminate at the apex, obtuse to rounded, sometimes slightly cordate at the base; glabrous, with slightly sunken midrib and prominent nerves and venation above; sparsely stellate-hirsute, soon glabrescent, with prominent nerves and slightly prominent venation beneath. Petiole 8-13 mm. Inflorescences axillary, 1-2 cm, 6-12-flowered. Pedicel 2-4 mm. Sepals transverse-oval, 1 & 2 ca 2.5 by 3-3.2 mm, 4&5 2.7-2.8 by 4.5-5 mm, stellate-hirsute outside (hairs with 3-5 subequal, up to 400 µ long branches). Corolla 8½ mm, tube 2½ mm; midpetaline field 4 by 3 mm, densely appressed-hairy (hairs 4-6-branched, often one branch stronger, up to 700 µ long); lobules 3.6 by 3 mm, without distinct venation, undulate at the margin. Stamens inserted 1-1.2 mm above the corolla-base; filament 1.5-1.7 mm long, 0.5-0.6 mm broad at the base; anther 2.2-2.3 mm long, 0.9-1 mm broad, 0.8 mm thick, acuminate (sterile acumen 0.5-0.6 mm) at the apex, slightly cordate at the base.
