Kaulfussia amelloides: hardy, t ft., blue or rose; the var.
The pinnae, except in a few filmy forms, are thick; in Kaulfussia large pores derived from stomata occur in the epidermis.
The sori are borne on the under surface of the pinnae, usually in a single row on either side of the midrib, but in Kaulfussia dotted over the expanded lamina.
(X 240.) association is closest in Danaea, where the individual sporangia of the elongated sorus, which is sunk in a depression of the leaf, open by pores; in Marattia and Kaulfussia (fig.
In all these genera there is an obvious similarity to the synangia of Kaulfussia, while in some respects Marattia or Danaea is approached.
