534 MERRILL: THE GENERIC NAME NAUCLEA OF LINNAEUS 



NAUCLEA Linn. Sp. PL ed. 2, 243. 1762. 



Sarcocephalus Afzel. ex R. Br. in Tukey's Congo App. 267. 

 1818. 



Cephalina Thonn. in Schumm. Beskr. Guin. PL 125. 1827. 



Platanocarpum EndL Gen. 557. 1838; Korth. Obs. NaucL 

 Ind. 18. 1839. 



Bancalus O. Ktze. Rev. Gen. PL 1:276. 1891. 



The type of the genus Nauclea, and the sole species cited under 

 this name in the original publication, is Nauclea orientalis Linn. 

 {Sarcocephalus cordatus Miq.). 



The type of the genus Cephalina Thonn. is Cephalina esculenta 

 Thonn., the only species cited ( = Sarcocephalus esculentus Afzel.). 



The type of the genus Platanocarpum EndL is not indicated 

 by that author; but he cites "Naucleae, sectio Nauclearia, §. 1. 

 DC. Prodr, IV. 343," the description applies to Nauclea of 

 Linnaeus {Sarcocephalus Afzel.), and the first three of the four 

 species placed by DeCandolle in the first section of Nauclearia 

 are Nauclea of Linnaeus {Sarcocephalus Afzel.). Interpreting 

 the genus upon the first species cited by DeCandolle, the type 

 would be Nauclea undulata Roxb. {Sarcocephalus undulatus 

 Miq.). Korthals' interpretation of Platanocarpuyn a year later 

 is based on two species: the first, Platanocarpum suhditum Korth. 

 ( = Sarcocephalus subditu^ Miq.) ; the second, Platanocarpum 

 cordatu7n Korth. {= Sarcocephalus cordatus Miq. = Nauclea 

 orientalis Linn . ) . 



Bancalus of O. Kuntze was based on '^Bancalus Rumph. 

 Herb. Amb. 3:84, t. 55. 1743," ostensibly because Bancalus 

 is an older name than Nauclea. Kuntze included in Bancalus 

 species of Sarcocephalus and of Nauclea as currently understood 

 by modern botanists; but whether Bancalus be typified by 

 the Rumphian plant or by the typexDf the Linnaean goim&Nauclea, 

 it is a synonym of Sarcocephalus Afzel. ( = Nauclea Linn.). Dalla 

 Torre and Harms are wrong in referring Bancalus O. Ktze. to 

 Nauclea Korth. as a synonym; it is a synonym of Nauclea Linn. 

 If Bancalus is to be interpreted as an exact equivalent of Nau- 

 clea of Linnaeus, the type is N. orientalis Linn., cited by O. 

 Kuntze as Bancalus orientalis (Linn.) O. Kuntze. If typified 

 by the plant Rumphius actually described and figured under
