Mr J. Smith has first accurately noticed the nature of the venation and of the sori in this
Fern. “ In some cases the venation of the fertile frond is free, and hears round sori, therefore
not differing from those of Polypodium ; but it is usual for the lower venules to anastomose
(as in the sterile frond), and produce round or oblong sori, presenting some affinity
with Meniscium and Goniopteris.’* J . Sm.
