XV. — On a new Species of Lycopodites, Goldenherg {L. 

 Stockii) , from the Galciferous Sandstone Series of Scotland. 

 By R. KiDSTON, F.G.S. 



[Plate v.] 



The genus Lycopodites, as originally employed by Brong- 

 niart* and most of the older writers, did not contain any plant 

 which was really entitled to the name, in so far as it was 

 used to infer their closer affinity to the recent Lycopodium 

 than that held by the genus Lepidodendron j and Brongniart, 

 in his later writings, discarded his genus Lycopodites^ as sub- 

 sequent investigations had shown him that his original view 

 of the plants he included in it was founded on an erroneous 

 notion of their true nature f. 



Hence, when Goldenberg resuscitated the genus Lycopo- 

 dites^ it was used by him in an entirely different sense from 

 that to which it had been applied by previous writers, and in 

 fact was a new genus though under an old name. 



To enable us more clearly to appreciate the light in which 

 Goldenberg regarded his genus Lycopodites^ I quote his intro- 

 ductory remarks regarding it. 



Lycopodites, Goldenberg. 1855 f. 



" Branches with leaves placed spirally or in verticils. 

 Sporangia placed in the axils of the leaves or forming ter- 

 minal cones." 



" In the genus Lycopodites we place the true herbaceous 

 Lycopods of former ages, which agree in all essential points 

 so exactly with recent Lycopods that, at the most, they can 

 only be regarded as a subdivision of the genus Lycopodium. 



" The fossil plants included by Brongniart and others under 

 this name are probably only young twigs of Lepidodendron
