 similar to that already mentioned in the description of Hemitelia

This name was proposed by Zeiller^ for Upper Carboniferous 

 fertile pinnae of the Sphenopteroid type, bearing ovoid sporangia 

 either singly or in marginal groups of 2 to 5 at the ends of the 

 veins. The appearance of the apical cells occasionally suggests 

 the presence of a rudimentary annulus. Kidston has recorded 

 this type of fructification in Britain". Stur describes fertile 

 pinnules of the same type under the generic name Hapalopteris^'
