Lepidostrobus ; Cyperites was the name given to the leaves,

sections of iri’ stems, or the cast of the interior, were t 
at each end, so that the section became like the section of a Jentil. 
cA thie remarks are necessary to understand the ¢ racter of 
the fossils which I exhibit this evening. They have been sub 
ted to great pressure, and there are fragments of all the 
different portions of the plant. I will begin Be describing the —
