6 PP. REPORT OF PROGRESS. FONTAINE & WHITE. 



4, Flaggy Sandstones. 800 feet. 



5. Conglomerate with flat pebbles not fully exposed. 

 No. 2 is conglomeratic in many portions. The base of 



No. 5 was not seen. No coal was seen here in the group, 

 and, so far as observed, it is always wanting in the more 

 westerly outcrops. 



The Vespertine Flora. 



The collections made of Vespertine plants, are rather 

 meagre, hence caution must be used in making deductions 

 from the material obtained. The number of localities, how- 

 ever, affording plants is considerable, and as they are widely 

 separated we may consider that the facts observed, have 

 considerable weight in fixing the character of the flora. 



In the first place, we are struck by the distinctly charac- 

 terized fades, which would, in every collection made from 

 any locality, at once indicate its Vespertine age. Indeed 

 most of the plants do not pass above this group. Such as 

 do are cosmopolitan forms of wide vertical and horizontal 



range. 



Another noteworthy feature is that while the number of 

 individuals of a species at a given locality is often very 

 great, the number of species is small, and we find one or 

 two plants forming the entire flora. The most abundant 

 species found at the localities in W. Va. are the following : 



Lepidodendron Veltheimianum, Sternb. 



L Sternbergii, Brongt. 



Triphyllopteris Lescuriana, (Cyclopteris Lesc. of Meek.) 



T Virginiana, (C. . . . Virg. of Meek.) 



Archaeopteris (Cyclopteris, Daws. Noeggerathia, Lesq.) 



obtusa. Lesq. 



A Alleghanensis,(Cyclopteris All. of Meek.) 



A (Noeggerathia Bock. Lesq. ) Bockschiana, 



Goep. 



A (Palaeopteris Hib. Schimp.) Hibernica. 



Parb. 



Besides these, we find commonly, several species of Lepi- 

 dodendron allied to Veltheimianum ; several species of Ar- 

 chaeopteris of the type of A. Jacksoni, (Cyclopteris Jack- 

 soni. Daws.) ; one or more species of Triphyllopteris, all 

 not described as yet.
