Description..--Leaves narrow, linear-lanceolate in outline,
equally pointed at the apex and base, short petioted, ranging from
5 cm. to IO em. in length and from 8 ram. to 13 ram. in width.
Margins entire, M_drib stout below, tapering above, usually
somewhat flexuous. Secondaries more or less remote, abo_t Io
alternate pairs, branching fron_ the midrib at angles varying from
35 ° to 45 °, eamptodrome, of fine calibre and often obsolete.
This species was described by Newberry ir_ 1868 from the
Dakota Group. Lesquereux in his Flora of the Dakota Group
makes it one of the varieties of his Sali.v prote_eyolia, but it is
obviously entitled to independent specific rank. It has not heretofore
been known from the Rarltan formation, but is found to be
sparingly represented in the Upper beds at South Amboy. It is
pre-eminently a species which characterizes the Magothy and
allied formati_as from Marthas Vineyard to Alabama, being
especially abundant in New Jersey and Maryland,
Occurrence.--South Amboy.
