Berry : Mesozoic flora of the coastal plain 251 



midrib at an angle of 45^ and curving upward in parallel courses, 

 camptodrome. 



This is another species of Salix which it is difficult to define 



with precision. If the emphasis is laid upon the large size, thin 



texture, and rounded base, we have characters which are easily 



F 



recognized and which can be made constant by elimination. It is 

 apparently common in the Lower Raritan and has been reported 

 by Hollick (Joe, cit.) from Marthas Vineyard, the latter horizon 

 probably of Magothy age. I have queried the small leaf figured 

 by Hollick from Kreischerville, Staten Island, as it seems to be of a 

 different consistency although it may be only a small leaf of this 

 species. The latter author has tentatively included Salix matte- 

 wanensis Berry, which comes from the Magothy formation at 



J 



This is, in the writers judg- 



ment, perfectly distinct and represents a much smaller, less elon- 

 gated leaf, of a different consistency and venation. 



Unfortunately, the original name Salix membranacea is pre- 

 occupied, so that it becomes necessary to propose a new name. 



Occurrence : Sayreville, Woodbridge, Milltown. 



Collections: U. S. National Museum; N. Y. Botanical 



Garden. 



Salix pseudo-Hayei nom. nov. 



Amboy Clays 6"^, pL 42,/, 6-8. 1896. 



Leaves small, relatively short and broad, ovate -lanceolate, uni- 

 formly about 3 cm. in length by 1.1-1.4 cm. in greatest breadth, 

 which is about half way between the apex and base. Apex 

 acuminate. Base rounded. Margin entire. Petiole short. Mid- 

 rib slender and slightly curved. Secondaries fine, obscured in 

 some specimens, five or six pairs, alternate, camptodrome, branch- 

 ing from the midrib at an angle of about 45^ and curving upward. 



This species is not uncommon in the Raritan, although Professor 



Newberry fails to mention the exact localities from which he col- 



lected it. Later material has come from the Lower Raritan at 



Milltown. It has been compared with the Dakota group species, 



Salix Hayei Lesq., and with the arctic Tertiary Salix Raeana 



Heer, both of which it resembles in -general appearance. The 



Dakota group leaf, however, is coriaceous, with a coarse venation, 



blunt apex, and more narrow pointed base and is seen to be quite 



different from the Raritan species when careful comparisons are 



made.
