of which it resembles quite considerably. It is not an especially
well marked species in any event, and the two forms which
Prof. Newberry figures show considerable variability. Fragmentary
specimens of what the writer believes to be this species
are present in the collections from the Hylton Pits.
Occurrence.--Woodbridge, Hylton Pits.
Collections.--N. y. Botanical Garden.

Descrfptiou.--Leaves palmately trilobate, the lobes subeqnal,
linear in outline, subacute, divergent, the lateral lobes directed
transversely to the median lobe, the intervening sinuses being
deep and open and forming an angle of nearly forty-five degrees.
Margins entire. Base truncate. Petiole long and stout. Midrib
sto_t. Lateral primaries, which diverge from the top of the
petiole, also stout, but somewhat less so than the t_idrib. A
subsidiary lateral of finer calibre branches from the outside point
of origin of each lateral primary. Secondaries irregular, rather
straight, diverging from, the primaries at usually a wide angle,
their ends joined by a marginal vein.
This is a rather ill-defined and infrequent species and suggests
the leaf which Prof. Newberry figured as dralia groenlandica
Heer. A fra_oTnent has been reported by Hollick from Glen
Cove, Long Island, and an equally poor fragment is contained
in the present collections from South Amboy.
Occufrence.--VVoodbridge, South Amboy,
Collections.--U'. S. National Museum, N. Y. Botanical Garden.
