of the specimens approach quite closely to the small leaves of Andromeda 

 grandifolia Berry, which are more slender and apically attenuated than 

 in the normal sized leaves of the latter. 



This species was first described by Professor Heer in one of the earliest 

 published accounts of the Dakota group flora,, and it has since been found 

 to have a wide geographical range. It is one of the commonest fossils in 

 the Dakota sandstone, having been recorded from Minnesota, Kansas, and 

 Nebraska. In eastern North America it is recorded from the Atane beds 

 of Greenland, the Magothy formation on Marthas Vineyard, the Raritan 

 formation of New Jersey, the Magothy formation of New Jersey, Dela- 

 ware, and Maryland, the Black Creek formation of North Carolina, and 

 the Middendorf beds of South Carolina. In Alabama it is common in 

 the Tuscaloosa formation and extends into the lower Eutaw beds in Hale 

 County. 



The genus Andromeda of Linne has been much segregated by the subse- 

 quent taxonomists, and this is reflected in Schimper's proposal to refer 

 this species to the genus Leucothoe. However, the more comprehensive 

 name has obvious advantages for the paleobotanist in cases like this, 

 where it is impossible to discriminate between the various Ericaceous 

 genera with any degree of accuracy.
