Buxaceae
The Buxaceae are a small family of six genera and about 123 known species of flowering plants. They are shrubs and small trees, with a cosmopolitan distribution. A seventh genus, sometimes accepted in the past (Notobuxus), has been shown by genetic studies to be included within Buxus (Balthazar et al., 2000).

屬 黃楊屬(Buxus) 富貴草屬(Pachysandra) 野扇花屬(Sarcococca) 尖苞樹屬('Styloceras) 黄杨科只有4-5个属，共约90-120种，一般都是小型树或灌木，广泛分布在全世界各地，第五个属(Notobuxus)根据基因测定，和黄杨属合并(Balthazar et al., 2000)。 黄杨科被许多分类学家承认为一个独立的科，但有的分类学家将尖苞树属单独列为一科，有的分类学家将旱霸王科（Simmondsiaceae）归入黄杨科。克朗奎斯特分类法将黄杨科列入大戟目。 2003年修订的APG II 分类法确定黄杨科为真双子叶植物分支中一个独立的科，是真双子叶分支中比较原始早期分化出的一支，不属于任何一目，但建议可以和双颊果科合并，AP网建议和双颊果科合并成立一个黄杨目。 参考文献 Balthazar, M. von, Peter K.

The Buxaceae are a small family of six genera and about 123 known species of flowering plants. They are shrubs and small trees, with a cosmopolitan distribution. A seventh genus, sometimes accepted in the past (Notobuxus), has been shown by genetic studies to be included within Buxus (Balthazar et al., 2000).
The family is recognised by most taxonomists, and it is commonly known as the box family. However, its placement and circumscription has varied; some taxonomists treated Styloceras in its own family Stylocerataceae, Didymeles in its own family Didymelaceae, Haptanthus in Haptanthaceae (now all included in Buxaceae)), and formerly Simmondsia was included, which is not related and now usually placed in its own family Simmondsiaceae.
