MARTHAS VINEYARD CRETACEOUS PLANTS* 

 BY ARTHUR IIOLLICK 



[^Abstract] 



At the New York meeting of this Society, in December, 1880, Mr David White 

 read a i)aper entitled " Cretaceous Plants from ^Marthas Vineyard," which was pub- 

 lished in abstract in the proceedings of that meeting. Tlie author subsequent!}' 

 published a more extended account in the American Journal of Science for Feb- 

 ruary, 1890, and figured a few of the specimens whicli were most readily identified. 

 These jjapers were based upon material collected by the author and Professor Lester 

 F. Ward in tlie summer of 1889. During the present year all of the material col- 

 lected was turned over to me for examination and report, in addition to which 

 there were a few specimens o])tained personally during the summer of 1898. The 

 general results of the examination of this material it is the purpose of this paper 

 to give. 



As is well known, Cretaceous strata, extending from northern New Jersey, 

 through Staten island, Long island and ]\Iarthas Vineyard, but nuich contorted 

 and dismembered, are found in connection with the terminal moraine. Cretaceous 

 material, generally in the form of ferruginous shale, sandstone or concretions, has 

 been discovered, scattered through the moraine also, wherever it has been care- 

 fully ex])lored in this region. 



The exact stratigraphic relations of the strata, owing to their contortion, are diffi- 

 cult to determine, but theoretically they ought to represent the upper meml^ers 

 of the Amboy Clay series, and Professor Ward, in a forthcoming pai)ert on the 

 Potomac Formation, classes them with Professor Uhler's Albiru])ean and calls them 

 the "Island series." Now that the specimens have been subjected to critical ex- 

 amination and comparison, it is of interest to note how the paleontologic facts agree 

 with the stratigraphic theory. 



I have elsewhere made the comparison between the Cretaceous fossil leaves of
