*7. Broad Fissured Hartstongue. Mssim^latum. This 
also is irregularly cut on the margin, narrowing to the base 
and acute at the apex. Fine specimens are four inches 
wide in the middle. M. Hawkchurch. 
8. Laciniated Hartstongue. Laciniatum, W. The 
frond varies from three to nine inches in length. The leafy 
part is very much torn and forms roundish lobes which 
occasionally protrude themselves. It is narrow except near 
the apex, where it is of the usual width. Some plants have 
fronds divided at the apex. Sometimes a little horn appears 
at the end of the mid-rib and occasionally another horn 
beneath. The large rounded loles protruding beyond the 
narrow parts are the chief characteristics of this variety.

9. Suprasoriferous Hartstongue. Crenatodohatum, This 
has the margin, especially at the upper end of the frond, 
notched with roundish lobes, bub not torn as the preceding. 
The frond is also a little waved. The clusters of spores 
appear on the upper surface as large and distinct as those 
on the under surface. 
10. Earless Hartstongue. Besectum, M. This is 
remarkable from the absence of the auricle or ear-like lobe, 
which is generally at the base ^ ^ ^ 
margins are slightly waved 
coarsely toothed. The ears appear to be cut off and slightly 
rounded at the corner so that the Fern has a lance-shaped 
outline. M. Axminster. 
11. Laciniated Earless Hartstongue. Laciniato-resectum. 
W. This has the round, torn lobes of the laciniated variety, 
and has no auricles as was mentioned of the preceding. 
Sometimes, on one side of the midrib, the leafy part seems 
almost to have vanished away, and what remains is torn and 
jagged and otherwise unseemly. It frequently happens that 
at the top of the plant, for an inch together, there is no 
leaf at all except the mid-rib, and there are similar irregu- 
larities near the stalks. Axminster, at Cloakham Bridge. 
12. Lobed Arrow Hartstongue. Sagitatodohatum. M. 
This Fern is arrow-shaped at the base : the basal lobes are 
long, acute, directed downwards : the lobes at the sides are 
pointed and the head branches into flat, acute segments. M.
