 somewhat higher horizons in Georgia would indicate that its rarity in the 

 Tuscaloosa deposits may be more apparent than real.

Description. Leaves of variable size, narrowly lanceolate and often 

 falcate in general outline, with an acuminate apex and a cuneate base. 

 Length ranging from 6 cm. to 12 cm. in the middle part of the leaf. 

 Margins entire. Texture coriaceous. Midrib stout and flexuous. Secon- 

 daries strong, somewhat flexuous, branching from the midrib at acute 

 angles and arching upward in ascending camptodrome curves. Tertiaries 

 mostly simple, transverse, forming oblong areoles. 



This species is of the same general character as the other Cretaceous 

 species of Andromeda, with which it is strictly congeneric. It makes its 

 earliest appearance in the lower Earitan of New Jersey, where it is com- 

 mon. It is not uncommon in the overlying Magothy formation.
