14 THE PALEONTOLOGY OF MINNESOTA. 



IPlatunus, Ficus. Laurus. 



The general character of the leaf is that of A. kefersteini&nd A. nostratum Ung. 

 resembling some of the numerous forms of the species as figured by Heer, Fl. Tert. 

 Helv.. PI. LXXI. 



Hab. North side of the Big Cottonwood river, near New Ulm, Minnesota. 

 Mus. Beg. No. 5368. 



PLATANUS PRIM^EVA? Lesqx. 



Cret. Fl. p. 69, PL VII, f. 2. 



A large leaf, more than 12 cm. long, 10cm. broad in the middle. The base and 

 the borders all around are destroyed. The nervation is that of a Platanus and the 

 species would be identified with P. primceva Lesqx., I. c., if the lateral nerves and the 

 nervilles were not comparatively thinner. The identification with P. heeri Lesqx., 

 or another allied species, is rendered impossible by the destruction of the lower part 

 and of the borders of the leaf. 



Hob. North side of the Big Cottonwood river, near New Ulm, Minnesota.

PlCUS AUSTINIANA, Sp. HOV. 

 PLATE A, FIG. 5. 



First Annual Report, Minn Sur., p. 114. 



Leaves coriaceous, oblong, truncate or cordate at base, entire and undulate; nervation 

 pinnate, camptodrome; lateral nerves at an open angle of divergence 60, curving in areoles 

 at a distance from the borders, branching above into strong nervilles anastomosing at right 

 angles with the secondary nerves or their branches. 



This beautiful species is represented by two fragmentary leaves, one larger 

 (figured), broken at its upper part, recurved at base, the border being embedded into 

 the stone, thus appearing truncate, though probably cordate. The second specimen 

 is part of a much smaller leaf, showing only one side of the leaf less the point, with 

 the nervation deeply marked and perfectly distinct. The nervation is of the same 

 character as that of Ficus protogea Ett., Kreide Fl., v. Nieders, p. 15, PI. II, f. 5; a 

 species also represented by a mere fragment whose nervation is the only point 

 of affinity observable. 



Hab. North sideof the Cottonwood river, in North Star. Brown Co., and Austin, Mower Co., Minnesota.

LAURUS PLUTONIA? Heer. 



PLATE A. FIG. 6; PLATE R. FT 5. 



Leaves sub-coriaceous, lanceolate, narrowed from the middle upward to ja somewhat 

 long, blunt-pointed acumen, downward to a short petiole, very entire; primary nerve com-
