198 BERRY: MESOZOIC FLORA OF THE COASTAL PLAIN 
reported from the Tuscaloosa clays of Alabama, while the New 
Jersey Raritan has ten species, the Magothy two, the Dakota 
group six and Greenland five. It is represented in the Cenomanian 
of Europe and Saporta & Marion record seven species from the 
Paleocene of Belgium. It is also represented at later geological 
horizons, while several species are recorded from the Older Potomac 
beds.

CHoNDROPHYLLUM NorDENSKIOLDI Heer, Fl. Foss. Arct. 3°: 114. 
pl. 32. f. 11,12; pl. 30. f. 4b. 1874. PLATE 13, FIGURE I 
This leaf is intermediate in outline between C. Nordenskidldi 
and C. orbiculatum Heer, from the Atane beds of Greenland. It 
approaches the former in general outline and also resembles it 
more closely in the character of the venation, differing in the pos- 
session of a wider, apparently slightly sheathing base, although 
this feature as shown in the specimen may be due to pressure 
acting ona short and stout petiole. Outline somewhat obovate 
instead of oval. 
C. orbiculatum is not very different from Heer’s other species, 
but has a thicker midrib, pinnate secondaries, and orbicular form. 
Two additional species are referred to this genus from the New 
Jersey Raritan, both of which are entirely distinct from the Caro- 
lina leaf. In addition, C. orbiculatum has been reported from 
Staten Island, and Lesquereux has identified both this and Heer’s 
other species in the Dakota group, referring them to the genus 
Hedera where they may possibly rightly belong. The North 
Carolina material comes from one half mile below Blackmans Bluff 
on the upper Neuse river. 
MALVALES 
Pterospermites carolinensis sp. nov. PLATE 14, FIGURE 2 
Rather thick, broadly ovate leaves with a slightly cordate base, 
about 10 cm. long by 6.5 cm. broad. Margin entire except in the 
upper part of the leaf, where it was probably undulate as there is 
an indication of such on the left margin just below where the leaf 
is broken away. Petiole preserved for 1.5 cm., very stout. Mid- 
rib straight, stout, becoming enlarged below to join the petiole. 
Secondaries subopposite, strong, distant, two pairs branching from 
the base of the midrib, the lower at an angle of nearly go degrees, 
giving off several tertiaries which arch along the margin; the
