One genus and ca. eight species: E Asia; seven species (four endemic) in China.

Although the familial status of the Stachyuraceae has been generally accepted, its systematic position has been long controversial. It was considered related to Actinidiaceae, Clethraceae, Crossosomataceae, Flacourtiaceae, Hamamelidaceae, Staphyleaceae, Theaceae, or Violaceae by different authors based on evidence from embryology, seed anatomy, wood anatomy, palynology, or rbcL sequence data.

The reader may also wish to refer to two other recent studies of the family, by Chen (Acta Bot. Yunnan. 3: 125-137. 1981) and Tang et al. (Acta Phytotax. Sin. 21: 236-253. 1983).
