are in general entire or slightly repand, and like the fossil somewhat 

 variable. Cordia is certainly represented in the lower Eocene flora of the 

 Gulf region by forms that may be descendants of this Upper Cretaceous 

 species. The present form has been recorded from New Jersey. Staten 

 Island, Long Island, and Delaware, and is not rare in the lower beds of the 

 Tuscaloosa formation in the Alabama region.

Description. Species based on relatively large leaves which may be 

 regarded as bilobate or as dichotomously compound with bilobate leaflets. 

 The latter are linear lanceolate and markedly unsymmetrical in outline, 

 being narrowed and obtusely pointed distad and markedly inequilateral 

 proximad, one margin decurring for a distance of from 1 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 crn. to 

 6 cm. before forking dichotomously at an acute angle. Internally this 

 fork is often naked for a distance of 2 cm. to 3 cm. Secondaries fine, 

 numerous, subparallel ; they diverge from the midrib at wide angles and 

 become more or less lost in the leaf substance toward the margin, their 

 ends apparently united by flatly arched marginal veins. Areolation quad- 

 rangular. Margins entire. Texture coriaceous. 



The present species was described by Newberry from the middle Raritan 

 of Woodbridge, New Jersey, to which locality it has hitherto been con- 

 fined. It is obviously dicotyledonous, although the writer knows of no 

 similar existing forms. Among previously described fossil species it is
