i86 THE RARITAN FLORA. 



by Lesquereux and Newberry, it was an exceedingly variable 

 form. In plan it was trilobate, but the subsidiary lobes devel- 

 oped upon both the median and the lateral lobes obscures this 

 trilobate character and suggests Cissites parvifolins Berry^ of the 

 Albian of America and Europe, Cissites dentato-lohatus Lesq., 

 of the Dakota Group or Cissiis vitifolia Velen. of the Ceno- 

 manian of Bohemia. 



The primaries are stout and 3 in number; they may diverge 

 from the top of the stout petiole or be supra-basilar ; very often 

 the branches of the laterals approach so near the base that the 

 leaves have the appearance of being- palmately 5-veined. 



This species is common but fragmentary in the Raritan beds; 

 it ranges in size from 7 cm. to 10 cm. in length and from 6 cm. 

 to 12 cm. between the tips of the main lateral lobes. The sinuses 

 are all rounded, and the main ones may be deep or shallow. The 

 fragment from Long Island referred to this species by Hollick is, 

 as that writer remarks, exceedingly unsatisfactory and doubtful. 



The genus Cissites was instituted by Heer in 1866 for the 

 species Cissites insignis from the Dakota Group of Nebraska, 

 which presented various points of affinity with the genus Cissits 

 of Linne. It is a largely developed type in the upper half of the 

 Cretaceous period, but is replaced after the Eocene by forms 

 which are definitely referable to the modern allied genera such as 

 Cissiis, Vitis, etc.
