Your plant indeed I consider as precisely of
the same genus (if not species) with what you
have likewise been so good as to send to me under
the name of Alsophila peronniana. Both are
new to me; but surely this latter is not a true
Alsophila, which must have the capsules inserted

Aspidium angustum of Willd [Willdenow] is the same as
Aspid. asplenioides [Aspidium asplenioides].

Aspidium cristatum, from your country, is
exactly the same as ours.

Aspidium obstusum, as well as Aspidium
tenue of Ph., come very near Asp. fragile [Aspidium fragile].

Our Lycopodium clavatum had the leaves
always ciliated or toothed, Goldie's integrifolium [Lycopodium integrifolium]
has them quite entire: but your Lyc.
clavatum [Lycopodium clavatum] has some of both kinds of leaves.

Your Polypodium calcareum (dryopteris of
Mich. [Michaux]) is the same as our dryopteris & the
same as dryopteris I have from Boston. Neither
your plant, nor our dryopteris, is in
