There is good evidence that some of these fronds were really borne by Tree-ferns of the Carbo- niferous epoch, belonging, however, to a family quite distinct from that which includes our recent arborescent Ferns. A considerable variety of fructifications has been found in connection with fronds of the Pecopteris type; in many cases the reproductive characters point 1 The second generic name, Dactylotheca, is based on the fructification, which happens to be known in this species. It may be Pteridospermous (see Fig. 109, C)..
