Description. — "A foliis lanceolatis, basi attenuatis, integer- 

 rimis, nervo medio valido, transversium; striato, secundariis sub- 

 tilissimis, angulo acuto egredientibus, camptodromis." Heer, 

 1866. 



This species was first described by Prof. Heer, in one of the 

 earliest published accounts of the Dakota Group flora, and it has 

 since been found to have a wide geologiical and geographical 

 range. 



It is one of the commonest Cenomanian species occurring in 

 Minnesota, Kansas, Nebraska, in the west, and from Greenland 

 to Alabama, in the east. It is as common in the overlying 

 Magothy formation as it is in the Raritan, being recorded from 

 Marthas Vineyard, New Jersey, Delaware and Maryland. It is 

 alsoi present in the Bladen fo'rmatioo of North Carolina. 



The genus Andromeda of Linne has been much segregated by 

 subsequent botanists, and this is reflected in Schimper's proposal 

 to refer this species to Leucothoe. However, the more general 

 temi has obvious advantages for the paleobotanist in cases like 

 the present, where it is well-nigh impossible tO' segregate these 

 various Ericaceous genera with any degree of accuracy. 



Occurrence. — Newberry mentions no' specifi,c localities, but 

 says: "Found at nearly every locality opened." I have very
