ii8 'THE RARITAN FLORA. 



Woodbridge locality and are very close to Salix Lesqiierenxii 

 Berry, which is also present in the Raritan formation and wide- 

 spread in somewhat later deposits of Magothy and Dakota age or 

 their equivalents. It is possible that these two forms should be 

 united, in fact Hollick in a recent publication^ tentatively places 

 the Staten Island leaf referred to in the above citation under the 

 latter species. However, the writer does not feel justified in 

 making a change at the present time. Furthermore the Arrochar 

 locality is probably Raritan in age, while the Block Island and 

 Marthas Vineyard floras are probably of Magothy age. 



The whole question of a classification of all the Raritan Salix- 

 like leaves, which will be proper from a botanical standpoint, is 

 beset with the greatest difficulties, so that in the absence of 

 positive assurance the least possible amount of change is desirable.

 Sdix pseudo-Hayei Berr>% Bull. Torrey Club, vol. 36: 251, 1909. 



Description. — ^Leaves, small, relatively short and broad, ovate- 

 lanceolate in outline, unifonnly about 3 cm. in length, by i.i cm. 

 to 1.4 cm. in greatest breadth, which is about half way between 

 the apex and base. Apex acuminate. Base rounded. Margin 

 entire. P(etiole short. Midrib slender and slightly curved,. 

 Secondaries fine, obscured in some specimens, 5 or 6 pairs, alter- 

 nate, camptodrome ; they branch from the midrib at an angle of 

 about 45 ° and curve upward. 



This species is not uncommon in the Raritan, although Prof. 

 Newberr3r fails to mention the exact localities from which he 

 collected it. Later, material has come from the lower Raritan, 

 at Milltown. It has been compared with the Dakota group
