Description. Leaves orbicular-ovate in outline, 4 cm. to 10 cm. in 

 length by 2 em. to 5.5 cm. in width, petiolate. Apex acute, slightly 

 extended in one or two specimens. Base usually pronounced auriculate. 

 Petiole and midrib stout. Secondaries few, six or seven pairs, subopposite, 

 camptodrome. Texture smooth and subcoriaceous. 



This fine species is abundant and well preserved at Woodbridge in the 

 New Jersey Earitan and in the Magothy formation of Maryland and 

 Marthas Vineyard. Professor Newberry was somewhat uncertain as to its 

 relationship with Magnolia and compared it with Aristolochia, Polygo- 

 num, and Toxylon. The latter is the only genus which is at all sug- 

 gestive, and it furnishes no instances of auriculate bases, while this char- 

 acter of the base prevails in more than one modern species of Magnolia. 

 The outline, the consistency, and the venation are all in accord in point- 

 ing to Magnolia as the proper generic reference. This is one of those 

 forms mentioned from Marthas Vineyard by Professor Hitchcock in his 

 Geology of Massachusetts, published in 1841.
