ASPLENIUM. 
37 
by Mr. G. B. Wollaston Pinnules small. Length, 3 inches, and 
almost as much across the many-branched head. 
9. depauperatum, Wollaston. Found in 1853, at Black Head, 
County Clare, by Dr. Allchin ; and in 1855, at Rydal, by Mr. G. P. 
Wollaston ; also at Windermere, Arnside, and Bardsea. Interme- 
diate forms have also been found, and Mr. Clapham raised one of 
these from spores, which he called interruptum , and another, 
having the apex branched, ramo-iiepauperatum. The pinnules 
small, depauperate, and some wanting. 
10. Harovii, Moore. Found by 
Mr. G. B. Wollaston, and also at 
Portskewett, in Monmouthshire, by 
the late Colonel A. M. Jones, and re- 
cently by myself. A dwarf slender 
form, with numerous deeply cut pin- 
nae. Length, 5 inches. Trogyense is, 
however, a more marked form. 
11. hybridum, Lowe (confluens, 
Moore). Found, in 1870, on Levens 
Park wall, in Cumberland, by Mr. 
Stabler, of Levens. It is strikingly 
different from all other forms of 
confluens. An undoubted hybrid, pro- 
bably between A. trichomanes and A. 
marinum(the counterpart oiniicrodon, 
a hybrid of A. marinutti). Although 
copiously soriferous, there are no 
germinating spores, which is the case 
with the other hybrids. It is not im- 
possible that at some time or other 
a few spores may germinate, but 
with these hybrids this is extremely 
rare. 
When last seen, the plant was in 
the possession of Mr. Barnes, of 
Milnthorp ; it was then a grand 
specimen. The stem is much thicker 
than is the case with the ordinary 
form of Asplenium trichomanes. 
From near the base the pinnae are 
imbricate, and towards the apex con- 
fluent. Length 10 to 11 inches, width 
exceeding an inch. 
12. imbricatum, Clapham. Found, 
in 1863, at Knaresborough, by Mr. A. Clapham. 
I ig. 11. — Asplenium trichomanes, 
var. cnstatum (showing cresting). 
Pinnae scarcely 
stalked, large, and overlapping, the base square, and the margins 
prettily dentate. Length, 3 inches. 
13. incisum, Moore (excluding Mr. Clapham’s Settle plant). 
Found in Devon by' the Rev. W. S. Hore; near Burnley, by Mr. 
S. Gibson ; in Borrowdale, by Miss Wright ; and near Pyle, in
