Family. — Polypodies. 



A large and varied group. Capsules seated in circular 

 clusters directly on the back of the lateral veins. 



Genus. — Pseudathyeium, Neivm. 



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 Athyrium. 



Pseud ATHYRiuM alpestre. 



Aspidium alpestre, Hoppe, Taschenh. (1805), 21G; Schkuhr, 



58. 

 Polypodium alpestre, Koch. 

 Aspidium rhseticum, Swart z, Syn. Fil. 59. 

 Polypodium rhseticum. Woods, Tour. Fl. 423. 

 Pseudathyrium alpestre, Neivm. Phytol. iv. 370. 



Eliizoma 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 liimself, 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 sjjecimens of Fihx-femi- 

 na, says they first appear as "distinct round dots;" he had 

 probably seen the present species. 



Obs. — In Schkuhr's ' Handbook ' there is a reference to plate 60, 

 which plate is named Aspidium umbrosum, but certainly represents 

 this species.
