BRITISH FERNS . 
SCOLOPENDRIUM VULGARE POLYSCHIDES, or AN- 
GU STIFOLIUM of some authors, has a narrower linear 
frond, blunt at the apex, deeply and irregularly 
cut at the margin into roundish lobes. The sori are 
arranged in two irregular lines on each side the 
mid-rib. 
In ‘Nature-Printed Ferns/ Professor Findley and 
Mr. Moore have described sixty-six varieties of 
Scolopendrium; the distinctions are in many cases, 
however, so small as to be scarcely recognisable. 
Scolopendrium vulgare multifidum has the 
fronds forked, either near the apex or sometimes near 
the base. They are strap-shaped below, and then cut 
out into irregular fan-shaped expansions at the top. 
Sometimes they are cut into more acute lobes, and it 
is then known as Scolopendrium lobatum ,
