Type. Small terminal pieces of pinne. 
Dunker compares his species to P. Reichiana, Presl, and defines 
it as follows :— 
‘‘Pecopteris fronde pinnata (bipinnata?) pinnis lanceolatis, 
pinnulis linearibus apice obtusis adnatis, oppositis et alternis, venis 
tenerrimis obliquis instructis; rhachi tenui.” ! 
There are a few specimens in the Museum Collection which 
agree very closely with this species, and show certain characters 
which distinguish them from Cladophlebis Dunkeri, Schimp. They 
add very little to our knowledge of Dunker’s species. 
Frond bipinnate, pinne alternate or sub-opposite, long, and of 
uniform breadth ; pinnules approximate, obtusely pointed; venation 
of the Cladophlebis type. 
Ettingshausen has followed Dunker’s example in comparing 
Cladophlebis Browniana with Pecopteris Reichiana, Presl, and, 
indeed, includes the former as a synonym of the latter. Schimper, 
in the first volume of his standard work, takes the same view, 
but in the third volume he reverts to Dunker’s original specific 
designation. 
Schenk, as previously noted, has probably included under 
Dunker’s species examples of Cladophlebis Dunkeri, but in pl. xxvi. 
fig. 2, Paleeontographica, xix. he figures what I regard as a true 
Cladophlebis Browniana; the bluntly pointed approximate pinnules 
with entire margins are of rather a different type to that which 
characterizes the larger pinne of C. Dunkert. The latter species 
is a tripinnate form, but C. Browniana appears to be bipinnate.
