摘 要 ：本文修订了中国产山茱萸科单室茱萸属植物，归并异名长尾单室茱萸Mastixia caudatilimba C.Y．Wu ex Soong，恢复两个亚种等级，增加中国分布新记录种八蕊单室茱萸Mastixia euonymoides Prain.
Abstract:The genus Mastixia Bl. of China is revised in the present paper. The name Mastixia caudatilimba C.Y.Wu ex Soong is considered as a synonym of Mastixia euonymoides Prain. The species M. alternifolia Merr. et Chun in T.P.Song‘s work (1982) is evidently conspecific with M. cambodiana Pierre and the fore combination name M.pentandra Bl. ssp. cambodiana (Pierre) Matthew (1976) is accepted as the reasonable one. Furthermore, the species M. chinensis Merr. in T.P. Song‘s work is also restored to subspecific rank as M.pentandra Bl. subsp.chinensis (Merr.) Matthew (1976).
