Nauclea, Linn. Sp. Pl. ed. 2, 243; Roxb. Pl. Corom. i. 40; 
Korth. Obs. Naucl. Ind. p.18; Benth. et Hook. f. Gen. Pl. ii. 81. 
None of the plants called Nauclea by Linneus are now in this 
genus, though there is no doubt that he would have called those 
in it Nauclea if he had seen them. The oldest species now in 
the genus is Nauclea purpurea, Roxb.; but this plant is not very 
typical of the genus as it at present stands. It was Korthals 
who first gave the genus approximately its present limits, though 
he united with it 4dina and Breonia, neither of which genera he 
had, however, seen.
