Populus bolleana Masters, Gard. Chron. 18, p. 556, f. 96, (1882) 



Populus alba bolleana Masters. 1. c. 



No. 2467. (Cultivated) Notre Dame. The plant which bears 

 the same relationship to P. alba that P. italica Moencli, the Lom- 

 bardy poplar bears to A. or P. nigra Linn., does not spread 

 as rapidly as the common white poplar. It is very susceptible to 

 attacks of "borers" and other animal parasites and can scarcely 

 be said on this account to be quite hardy.
