Description. — ^Twig-s of a conifer, represented in clays by 

 crowded cylindrical branches of graceful aspect and slender fork- 

 ing- habit. The leaves are reduced almost tO' the vanishing point, 

 in fact most specimens fail to show any traces of leaves what- 

 ever, and it is possible that these spirally-arranged scale-like 

 leaves of Newberry's description may have been founded upon 

 deceptive material. 



These twigs are unjointed, an objection against their former 

 reference to the genus Frenelopsis. It has been suggested that 

 they represent decorticated specimens of Widdringtonites Reichii 

 (Ettings.) Heer, which is so common in the Raritan and over- 

 lying Magothy formation. The present species is recorded from 

 both Delaware and Maryland. 



Hollick and Jeffrey have shown (loc. cit), since the foregoing 

 was written, that the present species is not related to Frenelopsis, 

 but constitutes a distinct genus. 



Occurrence. — Woodbridge, South Amboy. 



Collections. — N. Y. Botanical Garden.
