Gress: Fossil Plants of the Dakota. 297 



II cm. to 22 cm. and in breadth from 1.9 cm. to 3.7 cm. It is usually 

 widest in the lower half of the leaf, although sometimes the base is 

 quite narrow and the widest part is toward the middle. In all un- 

 equivocal material the upper half of the leaf is narrow, and is pro- 

 duced as a long, slender, recurved tip, which is one of the character- 

 istic features of the species." Our specimens are about 15 cm. long 

 and between 2 and 3 cm. wide. 



Occurrence: Ellsworth County, Kansas, Dakota Sandstone (Cre- 

 taceous). Baron de Bayet Collection, Accession No. 2348, Carnegie 

 Museum, Pittsburgh, Pa. {Nos. 13, 15a, 13b). 



22. Ficus inasqualis Lesquereux. 



Ficus incequalis Lesquereux, The Flora of the Dakota Group, U. S. Geological 



Survey, Monograph XVII, 1892, p. 82, PL 49, figs. 6-8, and PI. 50, fig. 3. 



Description: A small portion of both apex and base is broken off. 

 The entire leaf is about 10 cm. long and 4.5 cm. wide at its widest 

 point, which is a little below the middle. In shape it is very much 

 like fig. 3, PI. 50, Lesq., op. cit. The sides are unequal, the one being 

 2.5 cm. and the other 2 cm. wide. The veining corresponds to the 

 description, op. cit. The leaf resembles also Magnolia speciosa. The 

 veining does not seem so distinct as it is in most of our specimens of 

 Magnolia, and the leaf also is a little smoother. The leaf may be 

 Magnolia speciosa, but the weight of evidence is in favor of the 

 species to which I have referred it.
