40 CONTRIBUTIONS TO PAL^ONTOLOGY 



In the discussion of most of the species in the Medicine Bow floras, suggestions 

 have been made, where possible, regarding what appear to be the more Hkely 

 family and generic relationships. In several new species, however, pending more 

 conclusive evidence, the leaves have been referred to the form genus Phyllites and 

 the seeds to Carpites. Systematic descriptions of previously described species have 

 been amended and new illustrations added where better material has been obtained. 



SYNONYMS AND CHANGES OF NAMES 



In the foUowing Ust all names which have been changed or synon^Tnized previ- 

 ously by other writers are inchided with those of the present report. The justifica- 

 tion for changes in species concepts is based on either more adequate or more 

 niunerous specimens, or on closer comparison with modern leaves. A fuU discussion 

 and complete bibUographic references of synonymous foi-ms are given under each 

 species in the systematic descriptions.
