406 GEOLOGICAL SUEVEY OF THE TERRITOEIES. 



branching outside, and connected by strong nervilles. This form ap- 

 pears at first speciifically different from Heer's species and also from the 

 leaf referred to it from Carbon. The leaves, 9 cent, broad and just as 

 long, have entire undulate borders, and the base merely cordate. One 

 of them, the best preserved, has only three pairs of secondary veins; 

 the lowest nearly as strong as the medial nerve, much divided outside, 

 ascending to the borders in an angle of divergence 50° ; the other, at a 

 more acute angle, 40°, branching, too, and connected with strong ner- 

 villes, the leaf, except for its form, appearing a leaf of Platanus. A 

 number of specimens, however, present marked differences intermedi- 

 ate between this leaf and those from Greenland, not only in the nerva- 

 tion, but in the basilar, auriculate borders, which, too, in one specimen, 

 are dentate. From this, as from the leaf described at Carbon, this 

 species appears very variable and well represented in our northern Lig- 

 nitic formation. I have not seen it as yet south of Carbon. The leaf 

 of ours has evidently a long petiole. 



Laurus primigenia, Ung., Fl. v. Sotzka, p. 38, PI. XIX, Figs. 1-4. - 



Leaves thick, coriaceous, lanceolate, tapering to a long petiole ; lower 

 secondary veins at an acute angle of divergence. 



One of the specimens represents the lower half of a leaf with a still 

 longer j)etiole, than marked by linger, loc. cit.', another has only theupper 

 part with the point broken. In both the character of nervation and the 

 form of the leaves agree with those of this species. The lowest pair of 

 secondary veins is at a more acute angle than the upper ones, and 

 ascends higher along- the borders. In one of the specimens some ner- 

 villes go out from the medial nerve as intermediate veinlets to the 

 secondary veins. The ultimate divisions, however, pass into round, 

 very small, areolae, the whole of the same type as in Laurus ]^rince]^s, 

 Heer. 



QuEEGUS PEALEi, Lsqs., Eept. 1871, p. 297. 



Many specimens of this fine species indicate the form of the leaves as 

 variable from broadly ovate iJointed to oval lanceolate-pointed. The 

 nervation and the form of the obtuse teeth is always as described in 

 Eept., loc. cit. One of these leaves is 7^ cent, long, only 2^ cent, 

 broad, while another is 4J cent, broad and only 5 cent. long. 



Represented, like the former, by specimens from all the localities of 

 this section. 



Platanus aoeeoides, Gopp. 



A good specimen, from six miles above Spring CaGon. 



Ficus AUEicuLATA, Lsqx. 



Described with specimens of Golden. The collection has an identifiable 

 fragment, representing the lower half of a leaf from the same locality 

 as the former. 



ClNNAMOMUM EOSSMASSLEEI, Heer. 



Eepresented by three specimens from six miles above Spring Canon.
