HoLLicK : Fossil Petal and Fklit from Kansas 104 



The fruit is plainly' that of a fig, and although some twenty- 

 three species oi luciis have been described from the Dakota group 

 they were based upon leaf-impressions alone. Only two speci- 

 mens of fruit were known and these were too ill-defined to admit 

 of specific description. (" Fruits o{ Ficiis," Lesq. Fl. Dak. Group, 

 85. //. 10. f. 7. 8. See our Fig. B, 2, 3.) They are incidentally 

 mentioned however as being associated with leaves of Ficiis iuae- 

 qualis Lesq. 



Specimens considerably more satisfactory were described and 

 figured by Heer in 1874, from the lower Atane beds of Green- 

 land — representing a geological horizon which is practically the 

 equivalent of the Dakota group — under the name Ficus protogaea 

 Heer* (H. Foss. Arct, 3-: 108. pi. jo. f. 5-7. See our Fig. B, 

 4. 5. 6.)

*The name Ficus protogaea was previously used by Ettingshausen, in 1867, in de- 

 scribing a fragmentary fossil leaf from the Cretaceous of Niederschoena in Saxony 

 (Sitzb. Akad. Wiss. Wien, Math. -Nat. CI. 55 : 249. //. 2. f. j. ) In any revision of 

 the genus it would therefore be necessary to rename these fruits. In this paper how- 

 ever it is not thought necessary to do anything more than to call attention to the fact.
