EQUIVALENCE OF BEDS IN EASTERN AND PLAINS PROVINCES 227 



The presence of a few species common to and characteristic of the Permian of 

 Europe. (4) The close relation of the new forms to species characteristic of the 

 European Permian. (5) The distinctly Permian facies of the flora as a whole 

 and its marked advance over the flora of the Upper Coal Measures. 



"The advance in the flora consists in the number of species and abundance 

 of individuals of callipterid and taeniopterid ferns and of the new genus Glenopteris, 

 which appears to be related on the one hand to callipterid ferns of Permian types 

 and on the other to the Triassic genera Cycadopteris and Lomaiopleris. 



"The evidence derived from the fossil plants seems to assure the reference of 

 the Wellington to the true Permian in the European sense. 



"The flora of the formations intervening between the Douglas formation 

 and the Wellington shales is much less satisfactorily known. A good deal of 

 interest is attached to the discovery of plants in the Wreford limestone, especially 

 as this formation has been recently regarded as the base of the Permian in Kansas. 

 Xine species have been obtained from this locality, as follows: Baiera sp., Callip- 

 teris conferta, Callipteris sp., Cardiocarpon sp., Carpolithes sp., Cordaites sp., 

 Rhabdocarpos sp., Sigillaria sp., Walchia pinniformis. The collection obtained 

 from this formation is small and comes from a single locality near Reece, Kansas. 

 The association of the flora so far as obtained is with the Wellington rather than 

 with Coal Measures flora. The presence of Walchia in abundance, and of callip- 

 terid ferns, along with the small species of seeds common to the Wellington, 

 together with the absence, so far as yet noted, of all of the common Coal Measures 

 species, gives the flora of the Wreford, as developed at Reece, a distinctive 

 Permian facies. 



"Coal Measures species, although rare in the collection obtained from the 

 Wreford limestone at the Reece locality, recur in some abundance in the horizon 

 at Washington, regarded by Beede as near the top of the Chase formation." 



Other lists of the Kansas plant fossils were given by D. White i 1

"The 13 species from Onaga communicated by Mr. Cievecceur are, as com- 

 pared with the floras of Lansing and Thayer, obviously of much later age. No 

 species in any way characteristic of the Lower Coal Measures or the Allegheny 

 formation remains. On the other hand, the ferns, either as individual species or 

 as phases of species having wide range, are clearly indicative of a stage at least 

 very high in the L'pper Carboniferous (Pennsylvanian). Nearly all the species 

 have been reported from either the Permian of Europe or the Dunkard formation 

 of the L'nited States, though, with the possible exception of Pecopteris newberriana, 

 none are distinctly characteristic of the Permian. Most of the forms present 

 occur in the Dunkard formation, whose flora was fully treated by Professors 

 Fontaine and I. C. White. 8 Yet the small flora from Onaga contains none of the
