7o THE RARITAN FLORA.<br />

50 ° circiter arrectis, late frondosis, lineari-lanceolatis, lobatodentatis<br />

vel basi pinnatifidis vel pinnati-partitis, laciniis ovatoobtusis<br />

apice denticulatis, vel ovato-acuminatis, sub-alternis,<br />

eonfertis, terminalibus longe lineari-laneeolatis, angustissimis,<br />

remote dentatis; nervis venisque strictis, arrectis, simplieibus vel<br />

saeplus furcatis, creberrimis." Debey and Eitings, 1859.<br />

A considerable number <strong>of</strong> specimens, which Pr<strong>of</strong>essor <strong>New</strong>berry<br />

identified as this species, were found in <strong>the</strong> <strong>Raritan</strong>. <strong>The</strong>y<br />

are more complete than <strong>the</strong> material so identified from elsewhere<br />

and show several minor differences. <strong>The</strong> lower pinna <strong>of</strong> <strong>the</strong><br />

former are widely separated, opposite or sub-opposite, and<br />

markedly dceurrent as well as unsymmetrical. Higher up, however,<br />

<strong>the</strong> pinnae become closer until <strong>the</strong>y finally unite, passing<br />

from notched to simple lobes, and <strong>the</strong>se latter are very similar<br />

to <strong>the</strong> type <strong>of</strong> <strong>the</strong> species. <strong>The</strong> texture is coriaceous and <strong>the</strong><br />

venation fine and IargeIy obsolete.<br />

<strong>The</strong> species is recorded from <strong>the</strong> Cenomanian <strong>of</strong> Greenlartd<br />

and Bohemia and <strong>the</strong> Senonian <strong>of</strong> Prussia and Bulgaria. <strong>The</strong><br />

remains referred to this species by Lesquereux from <strong>the</strong> much<br />

older horizon at Cape Lisbourne, Alaska, are found to be identical<br />

with Cladophlebis Huttoni (Dunk.) Font.<br />

Occurrence.--Woodbridge, South Amboy.<br />

Collections.--N. Y. Botanical Garden.<br />

lobes. Venation flabellate, about 7 veins enter <strong>the</strong> base <strong>of</strong> <strong>the</strong><br />
