Descrfption..--Trilobate leaves 04 variable size, 5 _- to 20 c_n..<br />
in length, by <strong>3.</strong>5 cm. to 13 cm. in breadth. Lobes pointed or<br />
obtuse, <strong>the</strong> middle one considerably <strong>the</strong> larger. Petiole short .<br />
and stout. Primaries branching from <strong>the</strong> cuneate base at an<br />
acute angle. Secondaries remote, camptodrome with <strong>the</strong> exception<br />
<strong>of</strong> <strong>the</strong> pair, <strong>of</strong> which one runs to <strong>the</strong> sinus on each side.<br />
Pr<strong>of</strong>. <strong>New</strong>ber W is very p_itive that this leaf is a true Soasa-<br />
Ira< with which view I entirely agree. <strong>The</strong> small leaf is <strong>the</strong><br />
exact counterpart <strong>of</strong> <strong>the</strong> modem Sassafras leaf it_ outline and<br />
venation, witR <strong>the</strong> exception that <strong>the</strong> primaries are basal. While<br />
no marginal veins are visible at <strong>the</strong> sinuses, <strong>the</strong> first secondaries<br />
leave <strong>the</strong> midrib and curve upward, runnin@ directly to. <strong>the</strong> sinuses<br />
as in <strong>the</strong> existing, Sassafras leaves, t-Iollick's specimen<br />
from Long Island, while fra_nentary, has a short branch running<br />
to <strong>the</strong> sinus in <strong>the</strong> half <strong>of</strong> <strong>the</strong> leaf-blade which is preserved.<br />
<strong>New</strong>berw's o<strong>the</strong>r figures each lack <strong>the</strong> basal portion o,f th_ blade<br />
and c¢1eo.f <strong>the</strong> lateral lobes; <strong>the</strong> lobes are more obtuse than irt<br />
his smaller specimen. While <strong>the</strong> sinus apgears to lack a marginal<br />
vein, <strong>the</strong> dispo.sitior_ <strong>of</strong> <strong>the</strong> secondaries and tertiaries in this<br />
region, is Sassafras-like.<br />
This species is common, but fragmentary in <strong>the</strong> <strong>Raritan</strong> at<br />
Woodbridge, and has also been reported from Long, Island and<br />
from <strong>the</strong> Magothy formation <strong>of</strong> <strong>New</strong> Jersey. It suggests somewhat<br />
