Thesporangia, which are either long or short-stalked, although theirdevelopment has not been followed, correspond so closely in themature state to those of the Polypodiaceae that there is littledoubt that their development is much the same.

In the former species the stalk is long andcomposed of three rows of cells, as in typical the sporangia in this species are also numerous longparaphyses (Fig. 193, D). The very interesting genus Matonia is represented by thetwo species M. pectinata and M. sannentosa, the latter butrecently discovered. Both belong to the Malayan Archipelago,.
