Shrubs, perhaps sometimes scandent, 1-3 m tall; branches compressed to subterete or subangled, strigose to strigillose or pilosulous often becoming glabrescent. Leaves equal to somewhat unequal; petiole 4-12 mm, strigose to strigillose; blade drying papery or thinly leathery, abaxially sometimes paler and/or brownish black speckled, oblong-obovate, elliptic-oblong, narrowly elliptic, or lanceolate, 4.5-17 × 1.5-6 cm, adaxially glabrous or sometimes strigillose to hirtellous along principal veins, abaxially glabrous to usually puberulent or hirtellous on blade and strigose to hirtellous along principal veins, base acute to cuneate, apex subacuminate to acuminate; secondary veins 4-7 pairs, in abaxial axils usually with pilosulous and usually also foveolate domatia; stipules persistent, shortly united around stem, broadly triangular, 4-7 mm, strigose to strigillose, long acuminate. Inflorescences 1-2 cm, densely strigose, strigillose, or hirtellous; bracts triangular to lanceolate, 0.5-2 mm, acute to acuminate; pedicels 2-3.5 mm. Calyx sparsely to densely strigose to strigillose; ovary portion obconic, 1-1.5 mm; limb campanulate, basal tubular portion 1.5-2 mm; lobes triangular to linear, 0.5-1 mm, acute. Corolla funnelform; tube 3-4 mm, outside strigose in upper part, inside villous at throat; lobes subovate to ligulate, 1.5-2 mm, outside puberulent to glabrous, obtuse to acute. Infructescences usually displaced to pseudoaxillary by subsequent stem growth. Fruit subglobose to somewhat oblate, 8-13 mm in diam., strigillose, pilosulous, or glabrous; seeds 2-4, compressed globose, 4-5 mm in diam. Fl. Apr-Jun, fr. Jun-Feb.
