Description. " C. foliis herbaceis, ellipticis, integerrimis, nervo medio 

 valido, nervis secundariis utrinque 4, oppositis, subtilibus, angulo acuto 

 egredientibus, distantibus, curvatis, camptodromis." Heer, 1882. 



The Grove Point leaf is a trifle narrower than the type, otherwise the 

 two are identical. Cornophyllum vetustum Newberry 1 from the Raritan 

 formation of New Jersey is possibly the same species. The features in 

 which the Maryland leaf differs from that of Newberry are its more lanceo- 

 late form : the symmetrical base ; the fewer secondaries (four to six, instead 

 of six to seven), which form a much more acute angle with the midrib, and 

 are more regular in their course ; the presence of the transverse tertiaries, 

 which are not visible in the Earitan leaf. The Grove Point leaf has a more 

 regular margin, a longer petiole, a stouter midrib and a more secondary 

 venation, all features in which the New Jersey leaf departs somewhat 

 from the typical leaves of Cornus. 



The present species was described from the Atane beds of Greenland to 

 which it is confined except for its occurrence in the Magothy formation of 

 Maryland. The generic reference is not positive and it may well be 

 questioned if this and allied forms that are commonly referred to Corn us 

 are not more properly referable to the Rhamnacece.
