In the later edition of Dixon's " Geology of Sussex," Carruthers 

 has furnished a list of plants of Wealden age ; the following 

 species being mentioned in addition to many of those included in 

 Topley's list l : 



Laccopteris Gopperti, Schimp. Mat- 



onidium Gopperti (Ett.).

Equi- 



A. brief sketch of the Wealden flora is given by Bogle 2 in a 

 paper on the " Wealden Strata of East Sussex," but no new species 

 are added to the lists of plants recorded by previous writers. 



The next communication on this subject, to which reference 

 need be made, is a note by E. H. Peyton in 1883, 3 in which the 

 following additional species are recorded from British Wealden 

 strata: Oleandridium (Tceniopteris] Beyrichii, Schenk, Pecopteris 

 Murchisoni, Dunk., and Pterophyllum Schaumlurgense (Dunk.) ; 

 there is also a specimen mentioned which is considered to be 

 probably Sphenopteris Gopperti^ Dunk. = Rujfordia Gopperti 

 (Dunk.).

 Wight," the following plants are mentioned as occurring in
