Remm'Jcs. Lepidodendron acuminatum appears to be only a 

 varietal form of Lepidodendron Veltheimianum^ with Avhich it 

 lias already been united by Schimper. 



Lepidodendron geniculatum is also merely a form of the 

 same species. 



Lepidodendron patens {Selaginites patens ^ Brongn.), from 

 the neighbourhood of Edinburgh, is likewise to be re- 

 ferred to Lepidodendron Veltheimianum. The peculiarities 

 of Brongniart's specimen arise from its mode of preservation.
