(G. T. G.) that the relation to any recent genus was at all a close one. The structure of the free part of the leaf was thoroughly worked out by M. Renault: in a species (L. esnostense) from the Lower Carboniferous rocks (Culm) of France ; certain leaves, associated with, and probably belonging to the British form L. Hickii, Watson, agree in several respects with the French specimens, while leaves of other British Lepidodendreae are also similar.
