Description. Leaves narrowly elliptical in outline, unusually uniform 

 in size and shape, 8.5 cm. to 13 cm. in length and 3.5 cm. to 4.5 cm. in 

 maximum width. Apex usually bluntly rounded, sometimes acute. Base 

 matching the apex. Petiole mediumly stout, 3 cm. to 4 cm. in length. 

 Midrib mediumly stout. Secondaries slender, often obsolete, about eleven 

 pairs, equidistant, parallel, camptodrome, branching from the midrib at 

 an angle of about 40. Tertiaries, when seen, transverse. Texture cori- 

 aceous. 



This species was described originally from the Dakota group of Kansas 

 by Professor Lesquereux. Professor Newberry described the Karitan 

 remains which are abundant at the Woodbridge locality as a new species, 

 and it has been kept distinct by Hollick, who recognized, however, its 

 practical identity with the Dakota group plant. There can be no ques- 

 tion that they belong to the same species, and it seems probable that 

 Magnolia van ingeni described by Hollick 1 should also be referred to the 

 same species. 



In addition to the localities already mentioned this species is found 

 on Marthas Vineyard and Long Island, in the Eutaw formation of 

 western Georgia, and in the Woodbine formation of the western Gulf 

 region (Texas). Characteristic specimens of this species are present in 

 the lower Tuscaloosa beds of Alabama.
