3. Waved Hartstongue. Undulatum, M. This has 
the margin much less curled or waved than the two 
preceding varieties, and the fronds narrower, and, unlike the 
two preceding, constantly fertile. The fronds are heart- 
shaped at the base, acute at the apex, the larger ones nearly 
a foot long and about an inch and a half wide. The plant is 
often confounded with the first variety. This is not un- 
common. 
4. Waved Variegated Hartstongue. Yariegatum, W. 
This plant is waved, as the preceding, and beautifully 
variegated with streaks of dark green on a light cream 
coloured ground. These streaks form a ridge on the surface 
of the leaf. M. Wootton.

5. Much-cleft Hartstongue. Yolyschides. Let us 
make another careful survey and look with an eagle eye 
into every crank or corner of our edges and ditches, or shady 
walls and wells, and we may chance to light on the Much- 
cleft Harts-tongue. The edges are a little crimped, but 
the great peculiarity here is, that the fronds are gashed and 
torn on each side, and jagged and notched on their edges, 
with gaps between the lobes or, as Moore describes it, an 
open sinus. The fronds are narrow, strap-shaped, from six 
inches to nearly a foot in length, and about three fourths of 
an inch wide. This Eern did not escape the notice of Bay, 
the great father of English botany, who designated it 
“ Bobart’s much-cleft Bhyllitis tortured by every lobe being 
jagged.”* This variety is by no means uncommon. 
6. Eissured Hartstongue. Fissum, This is wider than 
the much-cleft form about an inch and a half to two inches 
wide and is somewhat waved so that the gaps between the 
lobes are not very apparent. Some of the veins are netted 
and the clusters of spores are in oval patches scattered 
irregularly over the plant. The summit is usually blunt.
