POLYPODIUM Phegopteris, Linn. 
Pale Mountain Polypody. 
Polypodium Phegopteris; caudex very long, creeping; stipites stramineous, 
glossy-brown below, and scaly; fronds triangular-ovate, pinnate; pinnse 
approximate, sessile, confluent above, narrow-oblong, lanceolate, mostly 
opposite, deeply pinnatifid, hairy, lowermost pair distant, more or less de- 
flexed, and pointing forward; segments oblong, obtuse, nearly entire, lower¬ 
most ones adnato-decurrent and triangular; sori marginal, below the apex 
of the veins.

Hah. Moist mountain districts in various parts of England, Scotland, and Ire¬ 
land, chiefly in woods; rare in the warmer and more sunny counties of the 
south-east of England. 
In Europe this plant is widely extended, but it seems to pre¬ 
fer the cool and mountain regions. We possess it from Iceland 
and from the Alps of Switzerland; from the Altai and Siberia, as 
far east as Kamtchatka; Dr. Babington found it in Japan. In 
North America it seems equally abundant. Our specimens are 
from Greenland and Labrador, throughout Canada to the Rocky 
Mountains, and from the northern United States. It appears 
again on the north-west coast at King William’s Sound (Barclay). 
It is a very distinct species, having for its nearest affinity the 
North American Boh hexagonopterum , Mich., but the pinnse of 
the latter are bipinnatifid, and the basal segments are much more 
adnate with the rachis, and more detached. It is, too, a much 
more southern species in the United States, yet I should almost 
have been disposed to have considered it a southern form of P. 
Phegopteris , but that I find the sori to be quite terminal on 
the vein, a character really invalidating the most essential mark
