leaves somewhat thick, coarsely nerved, oblong-lanceolate, gradually nan-owed to the 

 short petiole ; borders distant/// dentate; secondary veins close, parallel, straight 

 to the teeth; nervilles distinct, in right angle to the veins.

We have of this species only the fragmentary specimen figured. The 

 leaf is slightly coriaceous, deeply marked by the secondary nerves and 

 their nervilles, and has the borders either regularly undulate or cut by 

 short teeth entered by the secondary veins, which pass nearly straight 

 from the middle nerve at an angle of divergence of 40°. The nervilles 

 divided in the middle of the areas by cross veinlets are close, and in 

 riffht ansles to the veins. The leaf is, in all its characters, similar to 

 Fi"\ 4 of PL VII., of the Fossil Flora of Alaska, where all the forms 

 described by Professor Heer have been found. In his description the 

 author recognizes five different varieties of his species, (b) being the one 

 to which this leaf is referable.

Fagus pseudo-ferruginea, sp. nov.

Leaf oho v ate, lanceolate-pointed, narrowed to the short petiole ; borders undulate; mid- 

 dle nerve thin; secondary veins craspedodrome, nearly straight in passing obliquely 

 to the borders." 



At first I considered this leaf as referable to Fagus Avdipofi, var. a, as 

 described by Abich ; but it presents some marked differences. The mid- 

 dle nerve is much narrower; the secondary veins more distant, less distinct, 

 dissolved quite near the borders, slightly curved, and also more open. 

 Tlie substance of the leaf is not as coarse, rather thin, and the base is 

 more acutely cuneate. But for the entire merely undulate borders, this 

 leaf should be identified with the living Fagus ferruginea, Ait., of the 

 present North American flora. By this character it resembles the Euro-
