Ccesa]phga Cookiana. Holtick in Newb., FL Amboy Clays, 94,
pl. 42, f. 49, 5o, I896.
Description._Leaflets of small size, elliptical in outline, entire,
r cnl. to. I. 4 can. in leng'th by 8 ram. or 9 torch,in breadth across
the middle. Apex and base about equally rounded. Texture
delicate. Midrib slender. Secondaries fe,a5 distant, about 3
subopposite pairs; they branch from the midrib at a wide angle,
about 8o °, and are, with the exception of the lower pair, straight
two-thirds of the distance to the margin, where they turn upward
in broadly rour_ded arches parallel with the margin to join the
secondaries next above.
The generic affinity of these fossils is doubtful. They almost
certainly represent the leaflets of some compound Iegmr_inous
leaf, and as nothing is to be gained by an attempt to redefine
their generic relations, they are left where they were placed by
their describer. The exact locality in the Raritan from which
they were collected remains unknown.
Occurrence.--Locality unM_own.
Collections.--N. Y. Botanical Garden..
