i82 THE RARITAN FLORA. 



the Raritan and a single, poorly defined leaf is referred to Acer 

 froni the insular Cretaceous flora. This absence of foliar re- 

 mains suggests that these remains are more properly comparable 

 with the winged seeds of conifers like those of Pimis, leaves of 

 which are cominon in the Raritan fo-rmation. Judged by the 

 modern representatives they are much more like Acer than Pinus 

 or other conifers, and they are therefore retained in the genus 

 where they were placed by Prof. Newbeny. 



In addition toi specimens from Woodbridge and South Amboy, 

 undoubtedly similar specimens are recorded from Marthas 

 Vineyard.

Description. — Leaves small, ovate in outline, 1.9 cm. or 2 cm. 

 in length and i.i cm. or 1.2 cm. in greatest breadth, which is at 

 the middle of the leaf. Apex rounded. Base cuneate, slightly

 verge at an acute angle and run parallel with the margin; the 

 upper are much shorter and more oblique ; all camptodrome. 



This species is based on the single specimen figured in Prof. 

 Newberry's monograph (loc. cit) and no additional examples 

 have come to light. In general appearance and venation it is con-
