MERRILL: THE GENERIC NAME NAUCLEA OF LINNAEUS 533 



making it the type and only species of the genus Nauclea. The 

 genus Nauclea, then, must be interpreted solely by a consideration 

 of the original publication of the name.^ Unfortunately Nauclea 

 orientalis Linn, is Sarcocephalus of all modern authors, but the 

 mere fact that a genus has been consistently misinterpreted is 

 no logical reason for ignoring the original application of the 

 name. Although Nauclea orientalis Linn, is in itself a mixture 

 of three species, the five references given by Linnaeus are con- 

 generic. 



The first reference is "Cephalanthus foliis oppositis Fl. zeyl. 

 53. Sp. pi. L p. 95," and this is Sarcocephalus cordatus Miq. 

 ( = Nauclea orientalis Linn.), and this number of the Flora Zey- 

 lanica is represented in Hermann's herbarium- by a drawing, 

 according to Trimen."^ This reference I consider typifies the 

 species. The second reference is to 'Tlatanocephalus citri 

 foliis bijugis, capite majore. Vaill. act. 1722, p. 259," which 

 in turn is based on "Katou Tsjaca, Rheede, Hortus Malabaricus 

 3:29, t. 33,'' and is Nauclea missionis W. & A. {Sarcocephalus 

 missio7iis Havil.).^ The third reference is to "Arbor indica, 

 fructu aggregato gioboso. Raj. hist. 1441," which is also based 

 on the same figure and description of Rheede as the above refer- 

 ence. The fourth reference is directly to "Katu Tsiacca Rheed. 

 Mai. 3, p. 29, t. 33,'' which, as noted above, is Nauclea missionis 

 W. & A. (Sarcocephalus missionis Havil.). The fifth reference 

 is a doubtful one to ''Bancalus Rumph. amb. 3, p. 84, t. 551" 

 and Kuntze has adopted Bancalus for the generic name in place 

 of Nauclea. Bancalus of Rumphius, however, is a Sarcocephalus 

 {= Nauclea of Linnaeus, not of other authors), a species closely 

 allied to Sarcocephalus junghuhiiii Miq., S. mitragynus Miq., 

 and S. tenuiflorus Havil. Cephalanthus orientalis Linn.,^ on 

 which Nauclea orientalis Linn.^ is based, presents the first, second, 

 and fourth of these citations.
