802 SYSTEMATIC PALEONTOLOGY 



Eamulis elongatis, virgatis, foliis omnino tectis, foliis subfalcatis, 

 angustis, apice valde attenuatis, uninerviis, ramis adultis pulvinis rhom- 

 beis obtectis." Heer, 1871. 



The American occurrences of cones of this species have heretofore been 

 referred to Sequoia gracillima Newberry, a composite made up of Geinitzia 

 cones and Widdringtonites foliage. These cones are exceedingly abundant 

 in the Magothy formation at Cliffwood Bluff, New Jersey, where those 

 that are more or less pyritized are washed out of the clays by storms and 

 high tides. When preserved as flattened lignitic inclusions they are some- 

 what different in appearance, and it is believed that material of this species 

 in the latter condition of preservation is the basis for the Raritan forms 

 which were identified as Microzamia gibba Corda by Newberry. 1 A single 

 cone is contained in the Magothy collections made along the Chesapeake 

 and Delaware Canal. 



The foliage, which resembles somewhat that of Sequoia reichenbachi 

 (Geinitz) Heer, as well as that of Cunningliamites squamosus Heer, shows 

 rather thick twigs with slender curved needle leaves interspersed with 

 small scale-like leaves. It has been found at a number of localities in this 

 country and is represented in the Tuscaloosa formation of Alabama by 

 several doubtful specimens.
