INTRODUCTION. xV 
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 !:— 
Laccopteris Gopperti, Schimp.=Mat- | Equisetwun Burehardti, Dunk. = Equi- 
onidium Gopperti (Ett.). setites Burchardti, Dunk. 
Pecopteris Geinitzii, Dunk. Pinites Dunkeri, Carr. 
Cycadeostrobus, sp. 
A brief sketch of the Wealden flora is given by Bogle? 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,° in which the 
following additional species are recorded from British Wealden 
strata :—Oleandridium (Teniopteris) Beyrichii, Schenk, Pecopteris 
Murchisoni, Dunk., and Pterophyllum Schaumburgense (Dunk.) ; 
there is also a specimen mentioned which is considered to be 
probably Sphenopteris Gopperti, Dunk. = Ruffordia Gépperti 
(Dunk.). 
In the later edition of Bristow’s ‘‘Geology of the Isle of 
Wight,” the following plants are mentioned as occurring in 
Wealden strata‘: — 
Pinites Carruthersi, Gardn. Cyeadeostrobus turnidus, Carr. 
P. Dunkeri, Mant. C. Watlkeri, Carr.
