Corolla urceolate, 6 mm long, stout, terete, tips exclusively and densely sub-appressed-setose. Leaves elliptic to subovate-elliptic, apex obtuse or broadly attenuate, the terminal gland callous and protruding, base cuneate, coriaceous, dark green above, greyish or light green below, when young appressedly rufous-setose on both faces, mature ones glabrous and rather shining above, dull beneath, ± densely set with short (0.5-1 mm) subappressed bristles, these rather early caducous except the bases which remain as blackish, glandular points, margin subrevolute, entire or almost so, 3-5(-6.5) by (1.3-)2.5-3.5(-4.5) cm, midrib markedly impressed above, raised beneath, nerves 2-3 pairs, 1 or 2 of them ± basal, the other from the midrib, all curved and high-ascending, slightly impressed above, somewhat raised beneath, or +-obscure; petiole grooved above, rufous-setose initially, glabrescent, (3-)4-8 by 1.5-2(-3) mm.

Bracteoles ovate-subacuminate, dorsally shortly subappressed or ± crisped-setulose, c. 2 mm. Calyx c. 4.5 mm, glabrous at the very base, otherwise ± densely and shortly setulose (at least in the upper part of the lobes), lobes spreading, triangular, subacute, c. 3 mm.
