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 />
