This name was invalid as originally described (as Cephalotaxus sinensis var. latifolia W. C. Cheng & L. K. Fu in W. C. Cheng & al., Acta Phytotax. Sin. 13(4): 86. 1975), and when later raised to species rank (L. K. Fu, Acta Phytotax. Sin. 22: 280. 1984), because two types (male and female) were designated. Cephalotaxus latifolia is more similar to C. harringtonii (Knight ex J. Forbes) K. Koch (C. drupacea Siebold & Zuccarini), from Japan and Korea, than to C. sinensis, with which it has been united by some authors. Cephalotaxus harringtonii has often been recorded from China (e.g., by S. Y. Hu, Taiwania 10: 25-26. 1964; A. Farjon, World Checkl. Bibliogr. Conif. 28. 1998), but apparently always as a misidentification of either C. latifolia or C. sinensis. Its leaves usually terminate in a relatively long cusp (as in C. sinensis) but occasional variants with very shortly mucronate leaves occur. These variants are similar to C. latifolia and C. mannii (C. hainanensis); their taxonomic status, and their relationship with the latter two taxa, need investigation.
