Hab. Guatemala.—Perhaps this should be joined with the nest, but the pinnæ and
pinnules are much less deeply cut, and the latter so broad that they are slightly
imbricated.

Very like A. maeroearpum in general habit, but quite different in fruit, d solenoptem,
M e tt, is a form of this, with the pinnules more sharply toothed, and cut down in the
lower part nearly or quite to the rachis ; a n d there is another plant (var te c to iB , Moore)
with niuch smaller sori, and the habit of the more finely divided forms of Filtx-
fcemina.
