££ Frond tripinnate ; racliis winged ; pinnae pinnate, above pinnatifid 
with decurrent sessile pinnules, lower pinnatifid with three to six bluntly- 
toothed segments, upper ones inciso-dentatc ; veins either simple or forked, 
diverging slightly into each lobe from the costa at an acute angle.” 
Obs . — This species was several times referred to as a Carboniferous 
fossil, as it was correlated with the Sphenopteris cilala, Bgt. (Ilym cn ophy Hites 
Grand ini, Gopp.) ; but this is not the case, the matter standing as follows. 
Brongniart originally described a JPecopteris alata from Australia, and a 
Sphenoptcris alata from the Carboniferous at Gaislautern, near Saarbriick, 
in Germany. Later on the JPecopteris alata was placed by Sternberg with 
Sphenoptcris, and has to be quoted as Sphenopteris alata, Stbg., or Bgt., sp.; 
and it cannot be therefore confounded with Brongniart’s original Sphenopteris 
alata, which by Goppert was referred to Hymenop hy Hites as II. Grandini, 
while Seliimper quoted it as Sphenopteris Grandini. Both Morris and 
M £ Coy quoted it in the sense of Brongniart’s JPecopteris alata, which there- 
fore, as such, could not be considered as a Carboniferous species.
