* A willow was collected by Charles E. Smith April 29, 1866, at Griffith's 

 Swamp and identified as S. cordata, and by Isaac C. Martindale and C. F. 

 Parker six days later half a mile below Kaighns Pt., and identified as S. 

 petiolaris. These form the basis for the record of Salix petiolaris Sm. within 

 our limits, but Mr. Bayard Long, who. has studied our local willows with 

 great care, is of the opinion that these are not petiolaris, but more likely 

 represent a hybrid between S. cordata and S. sericca.
