(Fl. d. Vorw., vol. ii, 1833, p. 215.) 



Chondrites flexuosus Ncwb. 



Chondrites Hexuosus Newb., Fl. Amboy Clays, ^4, pi. i, f. i, 

 4, 1896. Berry, Bull. N. Y. Bot. Gardens, vol. 3 : 100, 

 1903 (?). 



Description. — 'The remains so-named by Professor Newberry 

 consist of rather indefinite ramifying vegetable fibers supposedly 

 algal in their nature, but poorly defined and of uncertain biolog- 

 ical significance. They are strictly comparable with similar re- 

 mains described from abroad and so named from their resem- 

 blance to the modern genus Chondria Harvey of the Rhodome- 

 lacese. 



Schimper^ forty years ago listed eleven European species, 

 mostly Tertiary in age. A number of additional species have 

 been described since that time, including one from the Magothy 

 formation^ which is very similar to a Lower Senonian species of 

 Westphalia. Most of these species are, however, poorly pre- 

 served, and vague in their affinities. 



Occurrence. — Woodbridge, Sayreville. 



Collections. — N. Y. Botanical Garden.
