SALICALES. I I 7
This is another species of £alix 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 lower Raritan and has been reported
by Hollock (loc. 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 different, although it may be only a small leaf of this species.
The latter author has tentatively included Salix mattewanensis
Berry, which comes from, the Magothy formation at Cliffwood,
N. J., under this species. This is, in the writer's judgment,
perfectly, distinct and represents a much smMler, less elongated
leaf, of a different consistency and venation.
Unfortunately the original name Sa_ix membrcmacea is preoccupied,
so that it becomes necessary to propose a new name,
raritanensis being here suggested.
