Mr Brown, the author of the Genas, observes that it is very near Woodwardia (see our
T ab. X V II.), and that it has the same affinity with it that Asplentum has witlr Allantodia,
(B r .). Presl remarks that it does not differ from Woodwardia, except in the veins and
veinlets beneath being elevated, in having the sori rather distant from the costa, neither
immersed nor linear, and in the indusium being flat and arched.
