THE PERN FAMILIES OF BRITAIN. 
each, of which was again subdivided into smaller lobes. The 
plant becomes a spherical mass, and bears occasionally mar- 
ginal bulbils. 
S. V. digitatum (digitate). Fronds crested, with wide, flat, 
spreading divisions. 
S. V. fissum (cut). A pretty, narrowed form, with rather 
crispy, irregularly toothed margins. 
S. V. grandiceps (large-crested), Jno. Cousins (15). A 
splendid, robust variety, with heavy, spreading crests. It is 
peculiar in bearing frequently a sharp, cockspur-like projection 
near the bottom of the stalks. 
S. V. hemionitioides (Hemionitis-like). A small form, 
with fronds like barbed arrow-heads. 
S. V. inequale farcans (unequal-forked), Elworthy (16). 
An attenuated form, with ragged edges; fronds branching 
repeatedly, so as to form one large, irregular, fan-shaped crest. 
S. V. keratoides (horn-like). Syn. inequale cristatum 
(unequal-crested). Leafy portion very narrow, and head 
repeatedly divided into narrow, spreading divisions. 
S. V. laceratum (torn). Syn. endivaefolmm (endive-leaved) 
(5). An old variety, but one of the finest; in it the Hartstongue 
seems to aim at bearing pinnae like the other Ferns, the margin 
running out into long, sometimes crested, points; the basal lobes 
grow long, and bear decided flat crests; and finally, the frond tip 
bears frequently an enormous, frilly tassel, of great beauty. 
The plants vary much, the fronds sometimes being merely 
deeply and irregularly cut in the edges, basal lobes pointed, 
and terminal crests a small tuft only. It needs close treat- 
ment and free growth to display its best character. 
S. V. limbo-spermo cristatum (crested). Crests like fine 
fringe or lace. 
S. V. marginatum (margined). A singular form, found 
in several localities, with a raised line near the under margin 
of the fronds. 
S. V. marg. multiceps (much-crested). Same as last, with 
much-divided tips to the fronds. 
S. V. multiiidum (much-cleft). Spreading, flat, divided 
crests.
