Description. — ''Zweige ruthenformig unter spitzen Winkeln 

 getheilt, ziemlich diinn und schlank. Blatter zweierlei : die 

 schuppenformigen sehr verlang-ert, mit stumpfen, nicht abste- 

 henden Spitzen, locker dem Zweige aufsitzend; die der jiingeren 

 Sprosse blattartig, zweireihig am Zweige geordnet, lineal, breit, 

 dick, lederartig, vorne stumpf abgerundet, am Grunde merklich 

 verschmalert, von mehreren Langsstreifen durchzogen. Der 

 Zapfen unbekannt." Velenovsky 1885. 



This characteristic species described originally from the Ceno- 

 manian and Senonian of Bohemia may be readily recognized 

 by the form of the foliage — the flat lanceolate decurrent leaves 

 above and the short and appressed leaves below. As yet no 

 cones have been correlated with the leafy twigs in the American 

 material. Newberry says of this species that it is one of the 

 most common conifers of the Amboy clays, but mentions no 

 localities. The writer has only found it in the upper Raritan 

 at South Amboy, where it is very common, and at the Hylton 

 Pits, and it has been collected by Hollick from a probably equiv- 

 alent horizon at Kreischerville, Staten Island. 



In the overlying Magothy formation it is a common species, 

 with a recorded range from Marthas Vineyard to Maryland and 

 in the allied Bladen fonnation of Niorth Carolina. In the west 

 it occurs in the Judith River beds of Montana. It is a distinctly 

 younger element in the Raritan, allying that flora with the higher 

 Upper Cretaceous beds. 



Occurrences. — South Amboy, Hylton Pits. 



Collections. — N. Y. Botanical Garden, U. S. National Mu- 

 seum.
