This Fern is scattered nearly throughout Europe, extending from
Iceland and the Scandinavian countries southwards through tho
British Isles and continental Europe—Franco, Belgium, Holland,
Switzerland, Germany, Hungary, Croatia, and Transylvania, to
Spain, Northern Italy, and Greece. In Asia it is recorded from
Unalaschka and Kamtchatka, and also as extending ffiong the
chain of tho Altai. Algeria, iu Africa, is said to produce it ; whilst
in America, where it is sometimes known under tho name of
P . connectile, it is met with from Greenland and Labrador on tbo
eastern side, to Prince William’s Sound on the western, extending
southwards to the Rocky Mountains, to Canada, and to the northern
United States.
In cultivation tho Mountain Polypody rdquiros a free supply of
w a te r; and at tho samo time, in order that this supply may not
stagnate about its roots, very perfect drainage should bo provided.
Tills is best done by using broad shallow pots, and filling up about
two-thirds of tbeir depth vfith coarse ruhbly materials, to aUow of
tho percolation of the water, which, moreover, should not he too
continuously kept in feeders about the bottoms of tho pots. Turfy
peat mixed ivith leaf-mould'in tho proportions of two-thirds of tho
former to one-third of tho latter, and the whole wcU blended with
sand, forms a good compost. Tbe plants are hardy enough to endure
cold, but the beauty of the fronds, except in very favourable situations,
can only bo secured by keeping them, at least during the
growing season, in some place of shelter, of which none can he more
Lngenial to the plants than a cold shady frame, or its equivalent.
The samo remarks apply to Polypodmm Dryopteris.
Tho Mountain Polj-pody is not liable to much variation. The
only abnormal form '’which has been observed has some of the
pinnæ or pinnules bifid or multifid, and occasionally tbe apex of tbe
frond is similarly dmdod. I t also generally happens &a t where
dichotomous division takes place, the approximate portions are at
tho samo time depauperated. Depauperation, caused hy the punctures
of an insect at au early stage of development, sometimes
ooours, and might bo mistaken for a natural variation.
