Family. — Polypodies. 
A large and varied group. Capsules seated in circular 
clusters directly on the back of the lateral veins. 
Genus. — Pseudathyrium, Newm. 
Involucre wanting : clusters of capsules small, at first 
distinct, but often crowded when mature : first and second 
pinnules on each pinna, both above and below, of nearly 
corresponding size : ultimate divisions pointed but without 
spines : precisely the habit of Atliyrium. 
Pseudathyrium alpestre. 
Aspidium alpestre, Hoppe, Tasclienb. (1805), 21 G; Schkuhr, 
58. 
Polypodium alpestre, Kocli. 
Aspidium rheeticum, Swartz, Syn. Fil. 59. 
Polypodium rliseticum, Woods, Tour. FI. 423. 
Pseudathyrium alpestre, Newm. Pliytol. iv. 370. 
Rliizoma tufted ; stipes shorter than frond ; frond elon- 
gate, lanceolate, pinnate ; pinnae pinnate ; pinnules ap- 
proximate, lobed, lobes notched. 
Scotland. Three specimens are in the herbarium of Mr. 
Watson, gathered by himself, one in Canlochen Glen, For- 
farshire, a second on Ben Aulder, and a third on “ moun- 
tains near Dalwhinnie.” Mr. Watson thinks it possible 
that, as he went from Dalwhinnie to Ben Aulder, both the 
specimens last mentioned may be from the latter locality. 
Common in alpine districts of Europe, and will in all pro- 
bability prove so in Scotland. Lightfoot, in describing the 
clusters of capsules in the Scotch specimens of Filix-femi- 
na, says they first appear as “ distinct round dots; ” he had 
probably seen the present species. 
Ohs. — In Schkuhr’s ‘ Handbook ’ there is a reference to plate 00, 
which plate is named Aspidium umbrosum, but certainly represents 
this species.
