994 CRYPTOGAMIA. FILICES. Polypodium. 
Dicks. H. S. — Bolt. 42— H. Ox. xiv. 3. 23— Pluk. 179. 4. 
Scarcely more than a finger’s length. Stem greenish, not blackish purple. 
Linn. Leqfits six or seven on each side the stem; the lower ones oppo¬ 
site., the upper alternate; thick and opaque; generally cloven into five 
or seven segments, rounded at the ends. 
Opposite-leaved Polypody. P. license. Sw. Willd. Dicks. Acrostic 
chum license. Linn. Acr. alpinum. Bolt. Ben Lawers. Mr. Dickson. 
Woodsia Ilvensis. Br. Sm. E.) P. July—Sept. 
P. arvo'nicum. Leafits spear-shaped, wing-cleft, hairy underneath: 
stem hairy. 
( E. Bot. 2023. E.)— Pluk. 89. 5— FI. Dan. 391— Bolton believes his tab. 9 
to be the same plant.} 
From three to five inches high. Leafits seven to fifteen pairs, cloven on 
each side into five or six segments; spear-shaped, hairy underneath. 
Bolt. 
(Hairy Polypody. P. arvonicum. With. Sym. Hull. FI. Brit. P. hyper- 
boreum. Sw. Willd. E. Bot. Acr. license. Huds. Woodsia hyperborea. 
Br. Sm. E.) It is a very rare plant, even on Snowdon. Llwyd, in R. 
Syn. p. 119. On a moist black rock almost at the top of Clogwyn y 
Garnedd, facing the north-west, directly above the lower lake. Dr. Rich¬ 
ardson, ib. P. July—Sept. 
This seems sufficiently distinct from the P. license found on the Scottish 
Alps by Mr. Dickson. Mr. Griffith thinks that Bolt. t. 9. is only a very 
small and stiff plant of P. fragile gathered in a high and exposed situa¬ 
tion ; and that it is not the plant found by Mr. Llwyd in Ray’s Syn. 
(Swartz is also decidedly of opinion that this plant is different from 
P. license . E.) 
P. Phegop'teris. Lowermost leafits reflexed, each pair united at the 
base by a four-cornered little appendage. 
Bolt. 20 , ( the lowermost pair of leafits not accurately represented. E.)— H. Ox. 
xiv. 4. 17,jfl 3, the quadrangular appendage not expressed. 
Leafits spear-shaped, wing-cleft. Linn. Plant sometimes nineteen, and 
stalk twelve inches, high. Leafits , the lowermost pair not confluent as 
all the rest, and placed an inch and a half from the pair above it; in a 
vigorous plant bent almost back to back, in consequence of which, when 
dried and gummed on paper, they form an acute angle with the stalk, 
and might lead those who had not seen the plant growing, to suppose 
they grew in the same plane with the rest. Lobes semi-elliptical. 
Woodw. Whole plant hairy. 
Wood Polypody. (The specific name (peyor-spiQ, seems inappropriate, 
the plant not generally frequenting Beech woods. E.) Clefts of rocks in 
moist and shady places and woods, in Yorkshire, Westmoreland, Devon¬ 
shire, and the Lowlands of Scotland. Barrowfield Wood near Kendal; 
by the fall of Lowdore; near Derwent Water. Mr. Woodward. (In 
Cawsey Wood, and in Waskerley Bourn, Durham. Winch Guide. On 
the banks of Loch Lomond. Rev. T. Gisborne. E.) P. June—Oct. 
P. Oreop'teris. Leafits strap-spear-shaped: segments very entire, 
bluntish : clusters of capsules at the edges.
