Taxonomic status and nomenclature of Cephalotaxuslanceolata (Cephalotaxaceae).

The nomenclature of Cephalotaxuslanceolata is controversial. After a thorough literature investigation, the nomenclatural problems have been resolved. This name was published in W. C. Cheng et al. (1975) and, although ascribed to "K. M. Feng", there is no suggestion that the descriptive material in the protologue was provided by K. M. Feng. Under Art. 46.5 of the ICN, this name should be attributed to K. M. Feng ex W. C. Cheng et al. but not to K. M. Feng alone. It has been claimed that the name is an illegitimate later homonym of one published by Beissner in 1901, but Beissner never accepted this name in any of his publications and so, under Art. 36.1, he did not validly publish an earlier homonym. Cephalotaxuslanceolatus was first validly published in W. C. Cheng et al. (1975).
