Description from Flora of China
Shrubs, ca. 3 m tall; branches somewhat flattened becoming angled and sometimes shallowly channeled, sometimes flexuous, densely hirtellous or hispidulous to strigillose or strigose. Petiole 2-12 mm, densely hirtellous to strigillose or strigose; leaf blade drying membranous or thinly papery, green to yellowish green adaxially, brown or purplish brown abaxially, oblanceolate or oblong-lanceolate to elliptic, 7-21.5 × 2-6 cm, adaxially glabrous or scaberulous to sparsely hirtellous, hispidulous, or strigillose, abaxially glabrescent or densely to sparsely hirtellous or strigillose, base cuneate or acute, apex acute to acuminate; secondary veins 12-20 pairs; stipules ovate to triangular, 4-8 mm, densely strigillose or strigose to glabrous, acute to acuminate. Inflorescences congested-cymose, 1-1.5 × 1-1.5 cm, usually 5-10-flowered, densely hirtellous to strigose or strigillose, sessile or subsessile; bracts ovate to triangular or linear, 0.5-8 mm, situated at nodes, along axes, and usually in pairs and 0.5-2.5 mm immediately below flowers. Flowers sessile to shortly pedicellate, with pedicels to 1 mm. Calyx strigillose to pilosulous; ovary portion obconic, 0.5-1.5 mm; limb 2-2.5 mm, lobed for ca. 1/2 its length; lobes triangular to linear-lanceolate, acute. Corolla white or yellowish white, funnelform to tubular, outside glabrous; tube 4-6 mm; lobes ovate, 1-2 mm. Berry globose, ca. 8 mm in diam., densely hirtellous or hispidulous to strigillose, with stipe or pedicel elongating above paired bracts, up to 12 mm; seeds reddish yellow, ca. 1.5 × 1-1.5 mm. Fl. Mar-Jun, fr. May-Mar.
These varieties were recognized by W. C. Chen in FRPS (71(1): 362. 1999); some recently collected specimens seem to be intermediate but this species is poorly documented in general, so these are treated here at least for reference.
