Also collected by Henderson & Ramaley, 1905. Dr. M. A. 

 Howe has very kindly sent me a tracing of Saporta's figures of 

 P. Heerii of Europe. The one well-formed leaf he shows is 

 broader, and with a more tapering base than in our plant, and 

 does not impress one as being identical. The probability of iden- 

 tity being on general grounds so slight, I think it is best to con- 

 sider the Florissant plant distinct. 



Salix Ramaleyi sp. nov. 



Leaf about 1 1 cm. long, 23 mm. broad in middle ; base cuneate, 

 with an angle of about 70 , but tapering gradually to the petiole 

 (not terminating abruptly as in S. amygdalaefolia Lesq.) ; leaf 

 apparently thin and glabrous, the midrib strong for the basal 3 

 cm., beyond that weak ; secondary nerves, at middle of leaf, 

 diverging at an angle of about 45 °, and about 8 mm. apart, not 

 joining on lateral margins ; reticulations fairly distinct, not especially 

 fine ; apex tapering (the extreme apex lost) ; marginal serrations 



(4 



very sharp, about 



1.3 mm. long on inner, and 2.3 mm. on outer edge. 



By the venation, and the shape of the base, as well as the 

 larger size, this cannot be 5. amygdalaefolia, nor can I identify it 

 with any other species. At first sight, it struck me as resembling
