CONIFERALES. 87 



Twigs, evidently deciduous, thin and flat, spreading in one 

 plane, with pinnately arranged, symmetrical, opposite branches 

 which are covered with thin closely appressed semicircular cyclic 

 leaves, the outlines of which give to the fossil specimens that 

 peculiar geometrical pattern, which once seen is thereafter un- 

 mistakable. Professor Heer placed it among the Cupressiere 

 because of its resemblance to Liboccdnis, and while the fruit re- 

 mains unknown, even in the very abundant material from South 

 Carolina, there seems to be no valid ground for questioning this 

 relationship. When only the outlines of the twigs are preserved 

 the fossils have a very fern-like appearance, which served to mis- 

 lead the original describers. 



This exceedingly graceful and interesting conifer was origi- 

 nally described as a fern from the Prussian Senonian. Abundant 

 and better material subsequently collected from Greenland 

 enabled Professor Heer to determine its true nature. It is abun- 

 dant in the upper Raritan at South Amboy, but does not occur 

 elsewhere in that formation.
