MIOCENE FLOE A— BAD LANDS. 227 



P. balsamoides of the same author is described by Heer in "Fl. Alask.," 

 p. 26, pi. ii, fig. 3. The leaves are smaller, less deeply crenate, the second- 

 ary nerves closer, more curved. The fragment represented here has also 

 a great analogy of nervation to P. palceomelas, Sap., "Et.," ii, 2, p. 267, 

 pi, vii, fig. 10.

 Plate XL VII, Figs. 1-5. 



Leaves large, sabcoriaceous, oval, obtuse or blunt at the apex, rounded or sub- 

 cordate at base; medial nerve thick, enlarged at base and passing into a very thick 

 long petiole; secondary nerves narrow, at an acute angle of divergence, camptodrome, 

 with few branches; nervilles close, simple or rarely forking. 



The leaves vary from 10 to 15 centimeters long and from 7 to 8 broad. 



The medial nerve is thick, at least on the lower side of the leaves, as in 



fig. 2, and the petiole, 4 to 5 millimeters in diameter when flattened, is 



long, measuring in the same leaf 4 centimeters from its top to its broken 



end. As seen from the figures the base of the leaves is cordate or rounded.
