SALICALES. ■ 117 



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 

 recognized and which can be made constant by elimination. It 

 is apparently common in the low^r Raritan and has been re- 

 ported by Hollock (loc. cit.) from Marthas Vineyard, the latter 

 horizon probably oi Magothy age. I have queried the small leaf 

 figured by Hollick from Kreischerville, Staten Island, as it seems 

 to be different, although it may be only a small leaf of this species. 

 The latter author has tentatively included Salix mattewanensis 

 Berry, which comes fromi the Magothy formation at Cliffwood, 

 N. J., under this species. This is, in the writer's judgment, 

 perfectly distinct and represents a much smaller, less elongated 

 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, 

 raritanensis being here suggested.

Description. — ^Leaves elongate-lanceolate in outline, 7 cm. to 

 12 cm. in length by i cm. to 2 cm. in breadth, generally broadest 

 near the base and tapering upward to a long, narrow^, acuminate 

 tip. Base cuneate. A long curved petiole sometimes present. 

 Midrib slender, flexuous. Secondaries slender, numerous, branch- 

 ing from the midrib at acute angles and curving upward, campto- 

 drome, sometimes invisible. 



These leaves are often unsymmetrical, and their reference to 

 Salix is not conclusively established. They are common at the
