Nomenclature—WNotes on. George B. Sudworth; N. L. Britton; 
B. E. Fernow. . (Gard. and For. iv. 165, 166; 202; 213, 214; 
239). 
Mr. Sudworth favors the use of specific names identical with 
generic in binomials if the name has priority, and points out the 
fact that Megundo aceroides, Moench, which was originally de- 
scribed as Acer Negundo, L., should be called Megundo Negundo 
if the genus Megundo is to be maintained; likewise Catalpa 
bignonioides, Walt., would become Catalpa Catalpa, and Sassa- 
Sras officinale, Nees., would become Sassafras Sassafras. He 
refers to the use of this method by zoologists, and calls attention 
to Dr. Britton’s non-acceptance of it in his recent catalogue of 
the plants of New Jersey. 
Dr. Britton expresses himself in favor of the method, and 
states why he did not adopt it in the New Jersey Catalogue. 
He further favors the citation of the original author of the name 
only, as is done by the zoologists; as for example; Catalpa Ca- 
talpa (L.), not Catalpa Catalpa, Sudworth, nor Catalpa Catalpa 
(L.) Sudworth. 
Mr. Fernow favors the double citation. 
Mr. Sudworth, returning to the topic, maintains that inas- 
much as the genus B/adhia, Thunb., (1781), is equivalent to, and 
antedates Ardisia, Sw., (1797), the West Indian and Floridian — 
tree which has recently been known as Ardisia Pickeringta, 
originally published by Nuttall as Cyrilla paniculata, should be 
called Bladhia paniculata; also, that the name Persea Caro-
