 Weinmannia phenacophylla Cockerell, Bull. Amer. Mus. Nat Hist., vol. 24, 



1908, p. 93. 



According to Professor Cockerell, Weinmannia haydenii as figured 

 by Lesquereux in the Cretaceous and Tertiary Flora is not the same as 

 his earlier Rhus haydenii, which, if true, would leave the former with- 

 out a name. An examination of the type of Rhus haydenii convinces 

 me that Lesquereux was right in referring the seven figures in the 

 Cretaceous and Tertiary Flora as Weinn^annia haydenii; hence W. 

 'phenacophylla becomes superfluous. 



Both the Hambach and Scudder collections embrace well-marked 

 specimens that belong here. [Cat. No. 33,748, United States Na- 

 tional Museum.] 



WEINMANNIA INTEGRIFOLIA Lesquereux.
