KIDSTON: YORKSHIRE CARBONIFEROUS FLORA. tl 



Filiates trifoliolatiis Artis. PI. xi. 



Now the Sphenopteris trifoliolata Artis sp. 

 ' Elsecar New Colliery, in that part of the mine which is 

 near Milton Furnace.' 



Myriophyllites gracilis Artis PI. xii. 



Probably not distinct from Pinmdaria prosttata Artis sp.

Probably referable to C. varians Sternb.

Filicites miltoni Artis. PL xiv. 



Now Pecopteris miltoni i\rtis sp.

 Milton Furnace.' 



Euphorbites vulgaris Artis. PI. xv. 



From the examination of several specimens of this plant, 

 on some of which the leaf scars are much closer than on 

 that figured by Artis, I believe it to be a variety of Sigillaria 

 mamillaris Brongt. I therefore record it as Sig. inainillaris 

 Bgt. var. vulgaris Artis sp.

 Aphyllum cristatuin Artis. Pi. xvi. 



Probably a badly preserved specimen of Lepidodendron 

 aciileatuin Sternb.

Now Dactylotheca ( Pecopteris ) pliimosa Artis sp. 

 Elsecar New Colliery.
