INCERT.^ SEDIS. 219 



This species was based upon imperfect speciniiens which some- 

 what resemble Chondrophyllum orhiculatuni Heer. No' addi- 

 tional material is contained in the recent collections and the origi- 

 nal locality for the type remains unknown. 



Occurrence. — Locality unknown.

Description. — Leaves may be regarded as bilobate or as dicho- 

 tomously compound with bilobate leaflets. The latter are mark- 

 edly unsymmetrical, linear-lanceolate in outline. Distally they 

 are narrowed and obtusely pointed. The base is markedly un- 

 symmetrical, one margin decurring for a distance of from i cm. 

 to 2 cm. below the opposite margin. The extremely stout midrib 

 (or common winged petiole of a double leaf) runs straight for 

 a distance of 5 cm. to 6 cm., at which point it forks dichtomously 

 at an acute angle, the two stout branches running to the tips. 

 Internally this fork is naked for a distance of 2 cm. to 3 cm. of 

 each limb, from which point the inner laminae of the lobes curve 

 out until the lobe becomes equilateral or even broader on its 

 inner lamina. The secondary venation is fine ; the secondaries, 

 which are numerous and parallel, branch at a very large angle 

 and become lost in the leaf substance toward the margin, although 

 they seem to be camptodrome in their final course. 



In discussing these peculiar fossils, which are not uncommon 

 at the Woodbridge locality, Prof. Newberry compares them with 

 Haliserites Reichii^ reproducing Sternberg's figure on plate xiv., 

 fig. 5. This plant, which came from the greensand of Nieder- 

 schcena in Saxony (Cenomanian) was discovered by Reich and 

 named Fucoides dichotomus. Sternberg referred it to Haliser-
