13. Barren Hartstongue. Sterile, W. To a casual 
observer there is nothing peculiar in this variety. There 
are, however, some points deserving notice. — 1. It never 
has fructification. 2. It has a greasy appearance. 3. It 
has scarcely any heart-sbaped lobes at the base and is of a 
papery texture. 4. Some veins branch near their base, 
others near their apex, and others not at all. M. Wootton.

14. Lobed Hartstongue. Lobatum, Deah. When we 
find the Hartstongue forking at its head once or oftener, 
and this constantly happens in all the fronds of the plant, 
this may be pronounced to be the lobed variety. The mid- 
rib also divides with each division and the fructification lies 
on each side of the mid-rib. Not uncommon. 
15. Transversely Lobed Hartstongue. Transverso-lobatum, 
M. Here the lobes are curved so as to cross each other, 
and the lobes are generally again lobed at their apex. 
16. Much divided Hartstongue. Multijidum, Gray, 
This difiers from the lobed variety not only in having some 
fronds much more cleft at their points instead of being 
simply forked, but also in having the primary lobes wider 
and splitting into several smaller segments. Some fronds, 
however, are regular, and herein it difiers from the crested 
variety as also in lying in a dense, flat head, and in not being 
curled or twisted together, with a tasseled crest. Axminster.

17. Lingered Hartstongue. Digitatum, W. This 
difiers from the preceding in having both the stalks and the 
leafy parts branched. The leafy parts are branched both 
near the base and in the higher part. The branches or 
divisions lie flat, or in one plane, being hand-shaped, though 
they are much crowded and overlap one another. Old 
Gerarde calls this “ the Linger Harts-tongue, Phyllitis 
multifida.” In his description he states, ‘‘that the leaves
