lOO THE RARITAN FLORA. 



Whether or not they are closely related to the modern genus 

 Phyllocladus is still in doubt, although there are some excellent 

 arguments for such a relationship. While fossil remains of 

 undoubted relationship to- this genus are extremely rare, Gothan 

 describes wood of similar type from the Jurassic of the east 

 coast of Greenland, under the name of Phyllocladoxylon} 



Occurrence. — Newberry states that he had some hundreds of 

 specimens from the Amboy Clays, but gives no localities. The 

 writer has collected it from Florida Grove and vicinity.

A single incomplete specimen from Woodbridge is identified 

 by Prof. Newberry with this poorly characterized species of 

 Heer, which is based on very incomplete remains. It seems 

 almost certain that the apical curvature which the latter makes 

 as one of the characteristics of this species is simply accidental. 

 The generic relationship seems to be correct and it is probable 

 that Baiera leptopoda, Heer, from the same horizon in Greenland 

 belong to the same species. 



The genus is an old one, appearing late in the Paleozoic and 

 becoming widespread and very important in the Triassic and
