Taxonomic list

• Triphyllopteris Floral Zone of Read (1955). "The flora obtained by Meek (1880) came from somewhere in the interval of units 20-35 (measured section of Read, 1955). The precise horizon cannot be determined, because the old collection came from material removed during the excavation of the tunnel. Additional specimens cannot be obtained." Read (1955) p. 11. Revised Identification included in occurence list. Note: "The original specimen of Lepidodendropsis scobiniformis (Meek) Read, n. comb. came from Lewis Tunnel on the Chesapeake and Ohio Railroad in Alleghany county, Va, near White Sulphur Springs, W. Va.
