THE FERN FAMILIES OF BRITAIN. 
with oblong pinnules set on in radiating clusters of two or three, 
instead of being compressed into balls; tips of fronds end 
abruptly. 
A. F.-f. Frizelliae (Frizell’s) (6). This was a wild find, and 
is a most extraordinary vagary, the pinnse all being contracted 
into flattish balls, so that the fronds, when full length, would 
be little more than ^in. wide, resembling a huge form of 
Asplenium TricJiomanes more than anything else. The spores 
of this have yielded innumerable sub-varieties, the great 
majority of which are inconstant; very provokingly so, since 
a plant may stand and flourish steadfastly for several years, 
and then, apparently without any reason, throw up fronds in 
which the common form and the variety are mixed up any- 
how, rendering the plant worthless. 
A. F."f. Friz, cristatum (crested) (11). Narrow fronds, 
true to type, but expanding at the tips into a splendid, nearly 
circular, radiating crest, heavy and dense. 
A. F.-f. Friz, ramosissinmm (extremely branched) (5). A 
pretty and constant form, in which the fronds branch several 
times close to the ground, forming a dense, close tuft of small 
fronds true to the type. 
A. F.-f. Friz, ramosmn (branched) (19). Syn. Appleby- 
anum (Appleby’s). A full-sized variety, in which the tip of 
the frond branches out into a broad, flat crest, sometimes 5in. 
to 6in. wide, all the divisions bearing the contracted pinnse 
of the type. 
A. F.-f. Girdlestoneii (Girdlestone’s). Wild find. Exceed- 
ingly handsome. The pinnules next the main stem are wanting, 
but those on the remainder of the pinnse stalks are very long, 
slender, and numerous ; they are, in their turn, near their bases 
devoid of pinnulets, which are again deeply cut and numerous, 
giving the frond a very rich and luxuriant appearance peculiar 
to this variety. 
A. F.-f. glomeratnm (clustered) (15). A distinct form, 
cresting in same manner as corymbiferum (James), but more 
heavily. 
A. F.-f. ICalothrix (beautiful hair) (4). This stands alone 
among our British varieties for delicate beauty. It is not
