 and has been confused with Magnolia speciosa by both dewberry and 

 Ward.

Description. Leaves broadly oval to almost orbicular in outline, obtuse 

 or abruptly pointed above and rounded to a somewhat cuneate base below, 

 10 cm. to 12 cm. in length by 8.5 cm. to 9.5 cm. in maximum width. 

 Midrib stout, somewhat flexuous. Secondaries numerous, camptodrome 

 medianly stout, ten to twelve pairs ; they branch from the midrib at acute 

 angles, immediately curving outward, forming festoons near the margin, 

 which is somewhat undulate in one specimen which Professor Newberry 

 referred to this species. 



This species differs from its contemporaries, especially in its nearly 

 round outline; Professor Lesquereux finds a resemblance to Magnolia 

 inglefieldi Heer from Greenland, and it also suggests some of the Arctic 

 forms which have been referred to Magnolia capellinii Heer. 



While this species is reported from such widely separated points as 

 Marthas Vineyard and Kansas, it is nowhere abundant and is usually 

 poorly preserved, suggesting that the leaves were readily macerated. In 

 Alabama it appears to be confined to the lower Tuscaloosa.
