Large to suffruticose herbs, 0.2-1 m tall; branches densely puberulent, shortly pilosulous, or tomentulose. Leaves sometimes crowded at upper part of branches; petiole 0.7-1(-2) cm, densely puberulent to tomentulose; blade drying papery and grayish green, pale abaxially, obovate, elliptic, or oblong-obovate, (10-)12-23 × 4.5-10 cm, adaxially glabrous, abaxially densely puberulent to glabrescent on lamina and densely puberulent to tomentulose along veins, base acute to obtuse, apex cuspidate or acute; secondary veins 9-15 pairs; stipules lanceolate-oblong to ovate or narrowly triangular, 6.5-15 mm, glabrous to densely puberulent, densely parallel-veined to palmately veined, acute to shortly bilobed. Inflorescences terminal, globose; peduncle 3-10 mm; branched portion subcapitate to congested-cymose, subglobose, 2-3.5 cm; bracts ovate to lanceolate or obovate, 8-20 mm, densely puberulent, densely parallel-veined to palmately veined, acute to acuminate. Flowers subsessile. Calyx puberulent to glabrous; hypanthium portion subglobose to obconic, 1.5-2 mm; limb divided to base; lobes narrowly triangular to linear, 6-12 mm, densely longitudinally veined. Corolla yellow, tubular, outside puberulent to glabrous; tube 9-10 mm; lobes triangular to ovate, 1.5-2 mm. Berries subglobose, ca. 3.5 mm in diam., glabrous to puberulent, with pedicels often elongating, to 8 mm. Fl. Aug, fr. Oct-Dec.
