32. Supralineate Hartstongue. Supralineatum. M. 
Here is on the upper surface not a ridge, but a line formed 
by the receding of the outer skin from the edge of the leaf 
and this line running longitudinally or somewhat parallel to 
the mid-rib over a portion of the frond. M. Hawkchurch. 
Lyme. Monkton Wylde. Seaton. 
33. Pimpled Hartstongue. Muricatum, M. This is 
regular in size and form with its margin notched or some- 
what lobed. The veins bear elevated points or pimples here 
and there over the upper surface of the whole frond. M.

34. Margined Pimpled Hartstongue. Muricato-mar- 
ginatvm, P. This was found by Mrs. Thompson of South 
Lawn, Exeter, near Netherton, Sir Edward Prideaux’s seat. 
It resembles the two preceding varieties in having both a 
raised line on the under and pimples on the upper surface. 
The margin is finely fringed. Earway. 
35. Irregular Pimpled Hartstongue. 'Papilloso-ir- 
regulare, Monkman. This has projecting points or pimples 
on the upper surface. It has either the usual auricle or 
else a lobe at the base, above which the leafy portion is all 
but wanting for a third or half of the frond : the rest of the 
frond is almost regular in its outline, which is about an inch 
wide. M. Thorncombe.

36. Margined Hartstongue. Marginatum, M. Good 
specimens of this Eern are a foot or more high, an inch 
wide, and without the auricle at the base : the apex is acute 
and the margins are lobed or notched. On the under 
surface the outer skin of the leaf recedes and forms an inner 
line nearly parallel to the edge of the frond, as represented 
in the woodcut. Hence, such fronds are said to be marginate.
