I30 THE RARITAN FLORA. 



Moletein, Mo-ravia, ranging in length from 8.5 cm. to- 19 cm., 

 and in width from 4 cm. to- 7.5 cm. It is ovate-elliptical in 

 outline with the apex more or less produced and the base de- 

 current. The midrib and petiole are stout. The secondaries 

 are well marked, camptodrome; they number 7 to 9 pairs, and 

 are subopposite, branching from the midrib at an angle of about 

 45° and curving upward. The texture is coriaceous. 



This species, which was described originally from the Ceno- 

 manian of Moravia, has been found to; have a wide range in 

 America. Typical leaves occur in the Dakota Group which 

 range southward to Texas. It is present on Marthas Vineyard 

 and Long Island, and in the Magothy formation of New Jersey. 

 While not heretofore reported from the Raritan it would seem 

 sis if some of the leaves which Prof. Newberry described as 

 Magnolia auriculata should be referred to this species. They 

 range down in size, but this is also true of some of the western 

 leaves oi this species. Magnolia auriculata. was reported by 

 Prof. Ward from the Tuscaloosa formation of Alabama, but 

 all of the specimens so labelled, which have come into the writer's 

 hands for study, are closer to Magnolia speciosa, and not one 

 shows any tendency toward an auriculate base which is the main 

 characteristic of the former species. This may, of course, have 

 been a variable feature, as it is to a certain extent in the existing^ 

 Magnolia Fraseri Walt., and Magnolia macrophylla Michx., 

 but if it is worth anything at all in the fossils it is worth empha- 

 sizing. This is another species which tends to correlate the 

 Raritan with the Cenomanian of Europe.
