A NOTE ON NOMENCLATURE. 

 By B. Daydon Jackson, Sec.L.S. 



In the haste to discover startling novelties in nomenclature, it is 

 but natural that many mistakes should be made; the following in- 

 stance is worthy of attention as denoting a teudency to overlooli facts, 

 and to mislead others who have not access to the authors quoted. 



Professor C. S. Sargent, in his Silvn of Xoith America, ix. 27, 

 employs Sweet's name Fagus ainericana for a tree which has hitherto 

 been known as F. ferruginea Ait. ; he cites as his authority 

 Miinchhausen, Der JIausvater, v. 162 (1770). This work seems to 

 be scarce ; I did not know of the existence of a copy in London 

 until the printing of the Inde.v Keivensis was proceeding, and then I 

 found an imperfect copy in the library of the Linnean Society, 

 which had been in the possession of Linnfeus, but had not been 

 catalogued, and so escaped attention. I will extract the portions 

 which relate to the tree in question, so as to make clear the actual 

 position of facts. The title of the same memoir varies, as shown 

 by the use of parentheses in the following : — 



(Ausfiihrliches) Verzeichniss aller Baiime uud Stauden welche 

 in Deutschland (in freyer Luft) fortkommen (oder als solche 

 angesehen warden konnen). — Bd. v. Th. i. S. 79-365.
