,Descrlptlon.--Leaves oblanceolate or elongate-obovate in outline,
5-5 cm. to 7 cm. in length by I.9 cm. to 2.5 cm. in greatest
width. Margins entire. Apex obtusely rounded. Base somewhat
elongated, narrowly cuneate. Petiole present, stout. Midrib
stout below, rapidly diminishing in calibre. Secondaries
numerous, 8 to IO pairs, alternate, branching from the midrib
at angles of from 4o° to 45°, eamptodrome. When tertiary
venation is distinctly preserved the venation is more typical than
when only the secondaries are partially visible.
This species is well distributed in the Raritan and has also been
recorded from Long Island and Staten Island. The identificatioi1
of Myrsin6tes ? Gm_dini Lesq., with the eastern forms wi.th
which it is obviously identical extends the range eastward from
the Dakota Group of Kansas. It may be readily distingxfished
from the other Rartain species by its relatively narrow elongated
form. It is also present in undescribed collections of the writer
from, North Carolina and Alabama.
Occ_rrence.--South Amboy, Milltown.
Collections.--U. S. National Museum, N. Y. Botanical Garden.
