220 THE RARITAX FLORA. 



ites because of its fancied resemblance to a recent alga, Haliseris 

 polypodoides Kg. This plant is hardly a seaweed and seems to 

 be congeneric with the Raritan plant. It was, however, much 

 smaller and differed in other particulars. 



Another similar form is figured by Bronn^ as Haliserites 

 Reichii and described by Rossmassler and Cotta as a Chiropteris. 

 Schimper^ refers it to the genus Delesseria because of its resem- 

 blance to the modern Delesseria ruscifolia Ag. This plant also is 

 scarcely a seaweed, in fact, Rothpletz has recently proposed call- 

 ing it Phyllites Reichii^. It is exceedingly close to Fontainea 

 and is probably a dicotyledon. Still another similar plant is the 

 one described from the Cenomanian of Bohemia by Velenovsky 

 as Aralia fiircata'^. This undoubtedly belongs to the same genus 

 as the New Jersey plant and is compared by its describer with 

 the genera Jatropha, Vitex, Ciissonia, etc. It can hardly be re- 

 garded as belonging to the genus Aralia. 



Prof. Newberry states his preference for a relationship with 

 Hymenaea and Bauhinia and regards the genus Sapindopsis from 

 the older Potomac as related to the Raritan plant. The two are 

 entirely distinct, however, and the Raritan plants must remain 

 for the present, at least, in the form genus Fontainea, to which 

 Prof. Newberry referred them.
