Having demonstrated that logically, historically, and under 

 all rules of botanical nomenclature those species which have been 

 described under Sarcocephalus must be transferred to Nauclea, 

 it becomes necessary to establish a new generic name for the 

 more numerous species that have been described by many 

 authors since Linnaeus under the latter generic name. In my 

 quest for a published name I have even looked up the original 

 publications of the various synonyms placed under Cephalanthus 

 Linn., but none of them are available for the species that have 

 up to this time been, placed under Nauclea. Acrodryon Spreng. 

 (Syst. 1:386. 1825) is based on Cephalanthus orientalis Lour.i° 



'" Loureiro, Flora Cochinchinensis, 67. 1790, under Ce-phalanthus occidentalis: 

 "Si cum Ceph. Americano (milii non obvio) non converiiat, vocetur Ceph. 

 orientalis."
