KIDSTON: YORKSHIRE CARBONIFEROUS FLORA. 45 



' Hutton Collection,' and the evidence afforded by Lindley 

 and Hutton's plate itself, I think there is no doubt that the 

 fossil given by Lindley and Hutton (Vol. i, pi. iv) which 

 they name Lepidodendron sternbergii is identical with Lepid. 

 ophiurus Brongt. It is therefore very desirable that Lepid. 

 dichotomum and Lepid. ophiurus (whether they form two 

 species or are only different conditions of the same plant) 

 should be carefully collected. In the meantime I treat 

 them as distinct. They occur together in the same beds.
