Asiatic Russia, and from Siberia. The variety pallida, which is
scarcely different, is found in the south of Europe ivhere it spreads
from Italy and Spain, to Greece, as Avell as in Northern Africa.
Tho Aspidium argutum of Kaulfuss, from California, is merely
another rmriety, larger and moro developed. The Bryoptera rigida
of Dr. Asa Gray, found, though rarely, in Massachusetts, North
America, which acquires a larger size and more developed character
than tho European rigida, proves to belong to the spinulosa type.
Tho culture of this Fern is very similar to that of the other
larger growing kinds, except that it is more impatient of moisture,
and doubtless prefers a purer atmosphere. I t grows well in free
Avoll-drainod loamy soil ; and the fact of its range being almost if
not quite confined to limestone mountains, suggests that the use
of limestone among the soil may bo beneficial, though it is certainly
not essential to success. I t is of far more importance that the soil
should be kept moderately moist, and should be of such a texture,
as may at the samo time prevent any accumulation of stagnant
water. I t is increased hy separating the lateral crowns formod by
the caudex. The latter is the better for being somewhat elevated
above the soil in planting, for being decumbent in habit, it does not
when planted deeply, liberate its croAvn so readily as the more ereot-
habitod species.
Mr. Y'ollaston has noticed a variation in which the fronds or the
pinnæ, or both, are simply or multifidly divided at the apex ; and
Messrs. Stansfield and Son, of Todmorden, have a small ramose
form, obtained from Ingleton Fells, hut noither of these prove
to be constant forms.
THE CHESTED BHCKLEB FERN.
l a s t r e a c r i s t a t a .
L. fronds erect, narrow linear-ohlong or ohlong-lanoeolate, sub-
bipinnate or bipinnate ; serratures spinose-muoronate ; scales of the
stipes ovato, pallid, scattered; i n d u s i u m without marginal glands.
—(typo) : fronds narrow linear-oblong ; pinnæ short triangular ;
pinnules or segments oblong, nearly always connootod at the base,
crenate-serrate, or obscurely lobod, anterior and posterior ones of the
lower pinnæ nearly equal. [Plate XL.]
