Frond bipinnate, rachis stout, occasionally bifurcating into two 

 linear pinnae inclined to one another at a small angle (pi. vii., fig. 1). 

 The pinn£e bear crowded pinnules with apparently a thick lamina ; 

 the pinnules vary considerably in size, shape and venation, they may 

 be stout and broad and almost semicircular in form, deltoid or broadly 

 oval with slightly divergent forked veins passing into broad linear seg-

 at an acute angle. The pinnules are confluent at the base. In the
