Scotland. It was found so long since as 1841, but, from its
close resemblance to Athyrium, Eïlix-foemina, has not been till
just now recognized ; and it is probable that it may have been
gathered by many persons in many parts of the Highlands, and
passed by as the commoner species. The ascertained localities
have been thus obligingly communicated by Mr. Watson :—
Mountains near Dalwhinnie, Inverness-shire, 1841. Great Corrie
of Ben Aulder, Inverness-shire, 1841. Canlochen glen, Forfarshire,
1844.
This plant is no doubt the Aspidium alpestre of Hoppe ; and
is also the Aspidium rhæticum, of Swartz, and Polypodium rhoeti-
cum of Woods, according to Newman. There is, moreover,
reason to believe it is the Polypodium rhæticum of Linnæus, and
if this can be satisfactorily settled, the name rhæticum must
supersede that of alpestre. It has been already mentioned that
Mr. Newman constitutes it a new genus—Pseudathyrium.
