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 />
