Prof. C. S. Sargent has kindly permitted the perusal of proofs of his Catalogue of the- 

 Forest Trees of North America, a report soon to be published for the Tenth Census of 

 the United States, according to which several changes in nomenclature are required by 

 species in this catalogue, making them read thus : Quercus obtusiloba, Michx.; Q^ 

 PRiNOiDES, Willd., (Q. Prinus, vars. acuminata, Michx., and humilis, Marshall) ; Betu- 

 LA PAPYKiFEKA, Marshall CB. papyracea, Ait.) ; Alnus incana, Willd. [only the type 

 occurs here, while var. virescens, Watson (var. glauca, Regel, in part), ranges from the 

 Saskatchewan to British Columbia, and thence south in the mountains to New Mexico] ; 

 Alnus serkulata, Willd. ; and Abies balsamka. Miller. Of Populus balsamifera, L.,. 

 var. candicans. Gray, Prof. Sargent writes : " Rare and perhaps unknown in a wild 

 state ; very common in cultivation."
