of varieties, the most important of which are described below:
=A. F.-f. acrocladon= (summit-branched).* _fronds_ 9in. to 15in.
long, slender, bi- or tripinnate, the lower part very narrow, with
the apices of the pinnæ sometimes crested; upper portion of the
frond freely branched, divisions narrow and crested, the whole
forming a broad head.
=A. F.-f. acuminatum= (taper-pointed).* _fronds_ 9in. to 12in.
long, lanceolate-acuminate in outline, with closely set pinnæ,
which are similarly characterised, and particularly tapering at the
apices.
=A. F.-f. apiculatum= (apiculate).* _fronds_ 6in. to 15in. long,
2in. to 4in. broad, lanceolate-acuminate in outline, with variously
furcate apices; pinnæ closely set with distinctly acuminated
apices, and small roundish obtuse serrated pinnules.
=A. F.-f. Applebyanum= (Appleby's).* _fronds_ narrow, 12in. to
24in. long, with short blunt pinnæ, while the extremities are
dilated into a broad furcated crest, which is very striking upon
such a narrow frond.
=A. F.-f. Barnesii= (Barnes's).* _fronds_ 9in. to 15in. long, 3in.
to 4in. wide, lanceolate in outline, abrupt at the top, bipinnate;
pinnæ alternate, closely set, lanceolate, acutely pointed, with
densely set, narrow, acutely serrate pinnules, with a very
membranous texture.
=A. F.-f. calothrix= (beautiful-hair).* _fronds_ 9in. to 15in.
long, copiously divided into exquisitely fine segments, so that the
fronds present a very light and delicate appearance.
=A. F.-f. contortum= (contorted).* _fronds_ very diversified,
the various pinnæ occasionally combining the characters of the
varieties _Applebyanum_ and _Victoriæ_.
=A. F.-f. coronatum= (coronate).* _fronds_ 6in. to 12in. long, 2in.
wide; pinnæ distinctly forked, sometimes slightly crested at the
apices; the upper extremity of the frond copiously forked, and by
the ramification of the divisions a broad crest is formed, about
3in. to 4in. across.
=A. F.-f. corymbiferum= (corymbose).* _fronds_ 12in. to 18in. long,
4in. to 7in. broad, lanceolate-acuminate in general outline; pinnæ
closely set, usually forked and crested at the apices, while the
extremities of the fronds are dilated into broad crests, nearly or
quite as wide at the broadest portion of the frond.
=A. F.-f. crispum= (crispy or curled).* _fronds_ 6in. long, densely
set with very finely divided pinnæ, which are thickly curled,
presenting a crispy appearance.
=A. F.-f. dissectum= (dissected).* _fronds_ 6in. to 12in. long,
ovate or broadly lanceolate in form, with irregular and unequal
pinnæ; the pinnules also differ very much, and are deeply cut,
nearly down to the rachises.
=A. F.-f. Elworthii= (Elworth's).* _fronds_ 12in. to 20in. long,
lanceolate, tripinnate, terminated with a very dense crest, from
4in. to 6in. across; pinnæ and frequently the pinnules also more or
less forked and crested.
=A. F.-f. Fieldiæ= (Field's).* _fronds_ 12in. to 20in. long,
narrow, with regular or variously-forked divided pinnæ, sometimes
arranged crosswise, with a very graceful disposition.
=A. F.-f. Friselliæ= (Frisell's).* _fronds_ pendent, sometimes
2ft. long, rarely exceeding 1in. wide, bi- or tripinnate; pinnæ
alternate, imbricated, flabellate, with the margins of the pinnules
or ultimate divisions dentated.
=A. F.-f. grandiceps= (large-crested).* _fronds_ 9in. to 15in.
long, lanceolate in outline, copiously forked both at the
extremities of the pinnæ and frond. The latter is furnished with
a very large globose crest, which causes the frond to present a
beautifully arched appearance.
=A. F-f. Grantæ= (Grant's).* _fronds_ 9in. to 12in. long,
lanceolate, or broadly so, very thickly set with pinnæ, copiously
divided, with the apices of the latter turned up, so that the plant
has a crisp or bristly appearance.
=A. F.-f. Jonesii= (Jones's).* _fronds_ 12in. to 18in. long,
oblong-lanceolate in outline, slightly acuminate, bipinnate,
furnished at the extremities with a small crest; pinnæ alternate,
copiously forked and crested at the apices, even having larger
crests than the one at the upper extremity of the frond; pinnules
narrow, dentate, slightly crested.
=A. F.-f. minimum= (smallest).* _fronds_ 4in. to 6in. long, 1in.
wide, lanceolate, bipinnate; pinnules densely set, imbricated, and
crispy.
=A. F.-f. Moorei= (Moore's).* _fronds_ 4in. to 8in. long, linear,
terminated with a broad tasselled crest, 3in. or more in diameter;
pinnæ small, scattered, variously forked, crested, and slender.
=A. F.-f. multifidum= (many-fid).* A very vigorous growing variety,
producing fronds as large as those of the type, terminated with
large tasselled crests; pinnæ and pinnules narrow, the former
furnished with small crested apices. A variety known as _nanum_
much resembles the foregoing, but the crests are more dense, and
the fronds are usually not more than half the length.
=A. F.-f. pannosum= (pannose).* _fronds_ 10in. to 20in. long,
lanceolate in outline, from 4in. to 6in. in the broadest part, bi-
or (rarely) tripinnate; pinnæ thickly set, closely alternated,
lanceolate-acuminate in form, with deep cut pinnules, and
distinctly but irregularly lobed; the whole frond is frequently
tinged with reddish-purple.
=A. F.-f. plumosum= (feathery).* _fronds_ 12in. to 30in. long,
4in. to 10in. broad, broadly lanceolate in outline, tripinnate,
beautifully arched; pinnæ of the same form as the frond, copiously
divided; pinnules again divided into very fine segments. There are
several forms of this charming variety.
=A. F.-f. Pritchardii= (Pritchard's).* _fronds_ 12in. to 30in.
long, very narrow, tapering especially towards the apices; pinnæ
decussate, imbricate, rather irregular, with the margins of the
pinnules dentate. There is also a variety named _cristatum_, which
is finely crested at the apices of the pinnæ, and is particularly
striking.
=A. F.-f. ramosa= (branched).* _fronds_ 9in. to 12in. long, the
lower portion sparsely set with short irregular pinnæ, sharply cut
into finely dentate pinnules; the upper part is divided into two
main branches, which are again variously forked, and furnished with
short pinnæ, the ultimate divisions furcate and slightly crested.
=A. F.-f. scopæ= (heavily-crested).* _fronds_ 6in. to 16in. long,
with a few scattered irregular pinnæ along the main rachis; some
of the pinnæ are almost obsolete, while others are an inch long
with oblong-dentate pinnules and a heavy terminal crest; the upper
portion has several ramifications, each of which is copiously
forked and heavily crested, the whole forming a corymbose head 3in.
or 4in. in diameter, which gives the plant a pendent habit.
=A. F.-f. sub-lunatum= (half-crescent-shaped).* _fronds_ 9in. to
20in. long, less than 1in. wide, with curious alternated, nearly
crescent-shaped, much contracted pinnæ, sparingly divided, arching.
=A. F.-f. Victoriæ= (Victoria's).* _fronds_ long, lanceolate in
outline, with the apices crested, as well as those of the pinnæ;
the latter are forked at the base, the divisions being divergent,
and crossing those of the neighbouring pinnæ. A form named
_gracilis_ has narrower fronds, is more compact, and cresting
rather thicker. There is also another form named _lineare_, having
very small heavily crested fronds, and an extremely elegant
appearance. The foregoing are the most important varieties, but
a very comparative few of the total number. Although forms of an
essentially hardy species, the greater number--and particularly the
rarer sorts--should have a winter protection; or, what is far more
preferable and satisfactory, they should be grown in the frame or
temperate fernery.
