PolyctAMous Fi.oweks in Popults. — On the Ttli of Ai)ril I found a few pistillate 

 'dmant^ oi Pojiulua tremuloides with both kinds of tlowers, and on fast-day (the 11th 

 inst.,) I Ibund four small sized female trees that were more or less polygamous. 



On one of these trees nearly every ament tliat I examined had i)erfect flowers in 

 addition to tlie regular pistillate ones. In one instance tlie stigma was partially cov. 

 ered with pollen from the open anther which was apparently just in the act of discharg- 

 ing its pollen. 



The number of stamens in these tlowers varied from one to four. Usually two, or 

 three, but sometimes f;)ur stamens were arranged around tiic pistil, the disk being en- 

 larged for their accommodation. 



1 do not remember to have seen anj'thing of this kind mentioned before in con- 

 nection with this genus, but Prof. Goodale tells me that Mr. Bailey has noticed it in 

 Popuhis halsamifera, near Providence, R. I., and Mr. Watson, to whom T communicated 

 my specimens, says it has occurred among the willows. 



In looking at the poplars .soon after some recent cold rains I noticed that those 

 buds wliicli had pushed out the earliest, were so much injured that they would drop 

 oti" almost at a touch. P'/pu/nx treinnloidex — the sterile aments — was in full l)loom in 

 Medford on the 29th of March, and P. (/randidertUita the following week. 



It is gratifying to know that this genus is to be worked up anew by one so fully 

 competent for the task as Mr. Watson, and that all confusion is likely to be cleared 

 away, and the different species clearly and accurately defined. — (tKO. E. Davenport,
