ASPLENIUM. 43 
23. subserratum, Stansjield. Pinnae lax, long and narrow, bicre- 
nate, and the crenatures minutely serrate. 
*24. Thompsonae, Lowe. Found in North Devon by Mrs. 
Thompson. A plumose variety and only second to plumosum as 
a beautiful variety of this species. Very feather-like in appear- 
ance. Fronds narrower at the base. Pinnae long, narrow, and 
conspicuously auricled. The superior margin is crenato-serrate 
yet not deeply divided, whilst the inferior margin is very deeply 
cut into narrow segments. This applies to the upper half of the 
frond. Length, 12 inches. 
25. trapeziforme, Clapham. Found in Cloughton Bay, near 
Scarborough, by the late Mr. Clapham (the locality now destroyed 
by the falling of the cliffs). A similar form has been found in 
Cornwall, Devon, and in County Down. Dwarf, trapeziform, with 
brief blunt pinnae. Texture leathery. 
26. variabile, Monkman. Raised from spores by the late Mr. 
1 Clapham. The fronds sometimes branch and rebranch several 
times, no two being alike. It is of erect habit and trapeziform. 
Length, 8 inches, with a breadth across the ramose head sometimes 
as much as 4 inches. 
27. variegatum, Lowe. Found by myself in 1876 in a sea-cave 
at Auchmithy, where it is (or was) abundant. A form of Auch- 
mithianum, with fronds regularly variegated green and white. 
28. Wollastoni, Lowe (acutum, Wollaston). Found in Cornwall 
by Mr. J. Flerbert. An acutum, but not of Moore , hence the 
change of name. Pinnules very narrow and acute. Apex caudate. 
THE ALTERNATE-LEAVED SPLEENWORT. 
Asplenium Germanicum. — Weis. 
Another very dwarf rare species, growing in 
fissures of rocks up to an altitude of 1,000 feet. 
It is usually found growing with Asplenium sep- 
tentrionale, and may be a hybrid between that 
and Asplenium ruta-muraria. At all events, I 
have been unable to raise it from spores. 
The fronds are pale green, from 3 to 4 inches 
long, with a slender stipes of half the length of 
the frond. They are pinnate to sub-bipinnate, 
and have a halfway character between A. ruta- 
muraria and A. septentrionale. Sori linear, elon- 
gate, and central. 
It has been found on Helvellyn, Borrowdale, 
Scafell, Kyloe Rocks (Northumberland), and near 
Culborne (Somerset). In Wales, near Llanrwst, 
Llanberris, and Capel Curig. Some years ago I 
saw it growing and of large size in Cefn Cave. 
In Scotland it is recorded at Perth, Dunkeld 
(Stenton Rocks, where I failed to find it), Dun- F ron d ofAspienium 
fermline, Kelso, and near Hassendeen. In 1857 Germanicum.
