Shrubs 1-3 m tall. Flowering branchlets red-brown, 8-12 cm, 4-6-leaved, stellate hairy, hairs sometimes with central rays. Petiole 3-8 mm; leaf blade abaxially green, ovate or ovate-lanceolate, 5-8 × 1-3 cm, papery, abaxially sparsely 10-15-rayed stellate hairy, indumentum discontinuous, hairs along veins usually with central rays, adaxially sparsely 4- or 5-rayed stellate hairy, veins in 3-5 pairs, base rounded or broadly cuneate, margin serrulate and slightly revolute, apex acuminate or abruptly so. Cymose panicles 5-10 × 3-6 cm, many flowered; pedicels 3-5 mm. Calyx tube ca. 2.5 × 2 mm; lobes ovate, ca. 1.2 × 1 mm, densely yellow-brown stellate hairy. Petals induplicate, white, narrowly elliptic, 0.8-1.5 cm × ca. 6 mm. Outer stamens 8-10 mm; filaments 2-dentate at apex, teeth horizontal, not reaching anthers; anthers borne between filament teeth, stalked, oblong. Inner stamens shorter than outer ones; filaments 2-dentate at apex, rarely ligulate. Styles 3(or 4), longer than stamens. Capsule hemispheric, ca. 4 mm in diam., sparsely stellate hairy. Fl. Apr-May, fr. Aug-Oct. 2n = 130.
Cultivated, sometimes naturalized. Anhui, Fujian, Hubei, Jiangsu, Shandong, Yunnan, Zhejiang [native to Japan].
