Hab. Himalayas to Ceylon.—A. opacam, Kunze, is a large form, with herbaceous pinme
1 in. 1. Very doubtfully distinct from A. wionantliemum, but constantly plurisorous.

Hab. Penang, iifaciicn—Bojer’s Madagascar specimen, figured in “ Species Filicum,”
seems to be an example of this, which differs from the rest of the group by its densely
fibrillose rachis, and is not unlikely A. setosum, Desv.

faintly so, the base hastately auricled on one or both sides, often cordate ; texture
herbaceous ; veins fine and close, once or twice forked ; rachis chesnnt-brown

Hab. Canada to the West Indies, and Ecuador ; Cape Colony.—A. ebenoides, Scott, of
which a single root was found on tbe banks of the Schuykill above Philadelphia, looks
most like this ; but tbe pinnæ are not out down to the rachis, and the frond has an
elongated point which is only sinuated with a single row of sori on each side. Probably,
as suggested by Professor Eaton, this is A . Hendersoni of Honlston, figured by Lowe,
vol. 5, t. 12. This species recedes from the Trichomanes group towards A. formosum.
