318 D. WHITE POTTSVILLE SERIES ALONG NEW RIVER, W. VA. 



seen to be closely related to the flora of the main Sewanee coal of Ten- 

 nessee and of the " coal-bearing shale " of Washington county, Arkansas. 

 The material from the Cunard mine, opposite Sewell, is astonishingly 

 similar in most respects to that found at Rockwood or Tracy City, in the 

 former state. 



While the paleontologic evidence makes it reasonably certain that the 

 Sewell coal was formed at a time relatively near that of the main Sewanee 

 coal, the inference that they may be the same coal is far from demonstra- 

 tion. Only those who have a strong predisposition to discover the con- 

 tinuity of individual sandstones or coals throughout the Appalachian 

 basin will, possibly, anticipate from this evidence, perhaps largel}^ cir- 

 cumstantial in character, that the two valuable coking coals are the same, 

 the " Emory sandstone " above and the " Sewanee conglomerate " below 

 the coal in Tennessee being equivalent to the Home wood and upper Piney 

 Creek conglomerate respectively in the New River section. 



FOSSIL PLANTS OF THE '' HOMEWOOD SANDSTONES 



One other of the plant beds in the New River section deserves men- 

 tion, since its paleontologic affinities will serve as an additional illustra- 

 tion in the evidence touching upon the relation of the " Pottsville " of 

 Ohio to that of the central Appalachian region. 



From a parting in the Homewood sandstone (see X, figure 2) in the 

 vicinity of Anstid fragments of the following flora were gathered : 



Plants from Homewood Sandstone [see L, figure 2). 



Species. Stage or group. 



Archxopteris, n. sp., related closely to Ohio and Pennsylvania. 



Eremopteris, sp Ohio. 



Sphenopteris furcata, Brongn Ohio, Pennsylvania and Coal Measures. 



Sphenopteris cf. divaricata of Lesquereux, form. Tennessee. 



Pseudopecopteris cf. acuta of Lesquereux Coal Measures. 



Neuropteris, sp Ohio and Coal Measures. 



Odontopteris gracillima, Newb Ohio. 



Alethopteris cf. ambigua, Lx Coal Measures. 



Cardiocarpus bicuspidatus, (Stb.) Newb Ohio, Arkansas and Pennsylvania. 



Triletes, sp. 



A glance at the above list shows that we have here to do with a flora 

 the preponderant elements of which are characteristic of the Sharon coal 

 of Ohio. One of the species, a form identified by Professor Lesquereux 

 as Sphenopteris divaricata, is characteristic of the Sewanee stage of Ten-
