Description. — " Sphenopteris fronde tripinnata, apicem cersus bipin- 

 nata, pinnis alternis distantibus vel plus minus approximatis, pinnulis 

 alternis clavatis petiolatis apice laciniatis vel subemarginatis, laciniis 

 obovatis, cuneatis, nervis obsoletis, rhacibus tenerrimis canaliculatis." — 

 Dunker, 1846. 



Abundant material from the English Wealden has enabled Professor 

 Seward (lac. cit.) to considerably amplify our knowledge of this plajit 

 by his description of the fertile pinnae, which are considerably reduced 

 and bear scattered sporangia, the structure of which could not be made 

 out.
