COERELATION OF EARLY CRETACEOUS FLORAS. 89 



four centimetres iu leugth. They are quite similar to those figured by Heer iu the fossil 

 flora of Siberia. Heer refers them in the text to Pinus, and in the legend of one of his 

 plates to Cyclopitus, while he seems to believe that certain taxus-like fruits may be refer- 

 able to this plant. Schenck (Fossil Botany) refers them to Cyclopitus and seems to believe 

 that this genus is intermediate l)etweeu Abietinete and Taxinete. Fontaine refers very 

 similar leaves to the genus Cephalotaxopsis. Cyclopitus is described as having verticel- 

 late leaves, but there is no evidence of our species having had its leaves arranged in that 

 way. Schenck refers to the modern Scyadopitys as possibly allied. 



The leaves of this species have evidently been deciduous and drifted over the muddy 

 bottom in immense quantities. With them are sometimes found small ovate flattened 

 nutlets ; but whether connected with the leaves is uncertain. It is to be hoped that the 

 excavations for coal will disclose more perfect specimens.

A single winged seed referable to Pinus was found in the beds holding the above 

 species and raises the question of its possible alliance to that genus. The seed is rounded, 

 about 2 mm. iu diameter. The wing expands slightly toward the distal end, and with 

 the seed is about 1 cm. long, but its extremity is slightly broken, though it seems to be 

 obliquely truncate. The wing is smooth with a few obscure veins. 



Cephalotaxopsis (Sp.) 



Very imperfect fragments are found at Anthracite, possibly referable to this genus, 

 which belongs to the Lower Cretaceous.
