SALICALES. I 15
" Lrnfortm_ately, the name g!ven this species was used for another
by Forbes in _829, so that it becomes necessary to rename
it, and no name can be more appropriate than that of iis distin,
guished describer, Leo Lesquereux, for whom it is here named.
This is an exceedingly variable species, as might be expected
in a Salix, and Lesqnerenx established several varieties, of which
at least one, i. e. lin_arifolia, is referable to Sali_ ttex_wsa Newb.
Some of Lesquereux's forms are distiugu,ishable with difficulty
from the latter, and this is especially shown in the leaves which he
figures on Plate I of his Cretaveo_s and Tertiary- Flora. They
are, however, larger and somewhat more robust, of a thicker
texture and broadest near, the base, from which they taper up-
(yard to an exceedingly acuminate tip. In general, SatiJ:
Lesquereuxll is a relatively much broader, more ovate form with
more numerous and better seen secondaries and a longer petiole.
It is a characteristic Cenomanian species in both the east and the
west, and has even been reported from the Cretaceous of Argentina,
by Kurtz (lot. tit.). It is abundant in the Raritan format-ion,
both in the lower and upper beds.
