Qin-er Yang (杨亲二);

Shrubs or woody vines, rarely small trees or herbs. Leaves opposite, rarely verticillate, simple or pinnately compound; stipules absent or very small. Inflorescence basically cymose or with pairs of flowers sometimes joined toward bases of ovaries. Flowers bisexual, regular or irregular. Calyx 4- or 5-toothed or lobed; tube adnate to ovary. Corolla epigynous, gamopetalous; lobes 5, spreading, sometimes 2-lipped, mostly imbricate in bud. Stamens (4 or)5, arising from corolla tube, alternating with lobes; anthers free, 2-celled, opening by longitudinal slits, mostly introrse. Carpels 3–5, united; ovary inferior, 1–5-loculed; placenta axile; ovules 1 to many per locule, pendulous; style solitary; stigma capitate or lobed. Fruit a berry or a achene-like drupe, rarely a capsule. Seeds 1 to many; embryo small, straight; endosperm copious.

About thirteen genera and ca. 500 species: mostly in temperate regions of eastern North America and eastern Asia; twelve genera and ca. 200 species in China.
