The known flora of the rocks older than the Carboniferous sys- 

 tem, has until recently been very scanty, and is still not very 

 extensive. In Goeppert's recent memoir on the flora of the Silu- 

 rian, Devonian, and Lower Carboniferous rocks,* he enumerates 

 20 species as Silurian, but these are all admitted to be Algse, and 

 several of them are remains claimed by the zoologists as 

 zoophytes, or trails of worms and mollusks. In the Lower De- 

 vonian he knows but 6 species, five of which are Algje, and the 

 remaining one a Sigillaria. In the middle Devonian he gives but 

 one species, a land plant of the genus Sagenaria.. In the upper 

 Devonian the number rises to 57, of which all but 7 are terres- 

 trial plants, representing a large number of the genera occurring 

 ia the succeeding Carboniferous system. 



Goeppert does not include in his enumeration the plants from 

 the Devonian of Gasp6, described by the author in 1859,f hav- 

 ing seen only an abstract of the paper at the time of writing
