b. Foliis bifariis. 
x Foliis indivisis. 
7. J. asplenioides, caule ascendente, ramoso : foliis obovato-rotundatis, ciliato-dentatis, 
subrecurvis ; fructu terminali, lateralique; calycibus oblongis, compressis, obliquis; 
ore truncato, subciliato. (Tab. xiv.) 
J. asplenioides. Wahl. Lapp. p. 395. Mohr, FI. Crypt. Germ. p. 420. 
The male fructification of this species I found in woods at Berry Pomeroy Castle, 
Devonshire, in great abundance in March and April. 
8. J spimtlosa, caule erecto, ramoso : foliis obovatis, recurvatis, bine margine apieeque 
dentato-spinulosis : fructu laterali, axillarique ; calycibus subrotundis, compressis ; 
ore truncato, ciliato. (Tab. xiv.) 
In Devonshire, particularly in the mountainous parts, J. spinulosa is plentiful ; but 
in the plains of England, I know of only one habitat, near Rufus’ stone in the New Forest, 
Hants., where it was gathered by Mr. Lyell. At Powerscourt waterfall, near Dublin, 
Dr. Taylor finds it with calyces, but never with capsules j and Mr. Lyell in the same state, 
on rocks above the summit of Stock-gill Force, Cumberland. 
Another var., which may be called y foliis minutis apice bidentatis, has been found by 
Mr. Lyell, at Keswick, and by the late Miss Hutchins and Mr. Mackay, in Ireland. 
9. J. decipiens, caule erecto, flexuoso, subsimplice : foliis inferioribus minoribus, ovatis, 
integerrimis ; superioribus rotundato-ovatis seu subquadratis, dente uno alterove 
sparso, spiuiformi. (Tab. l.) 
10. J. Donuiana, caule erecto, subsimplice, filiformi, flexuoso : foliis arete imbricatis, 
subhorizontalibus, oblongo-ovatis, concavis, apice bidentatis, falcato-secundis. — 
(Tab. xxxix.) 
11. J. pumila, caule ascendente, simpliciusculo : foliis elliptico-ovatis : fructu terminali; 
calycibus oblongo-ovatis, acuminatis ; ore contracto, denticulato. (Tab. xvii.) 
Mr. Lyell finds this at Kinnordy, Kerriemuir, Scotland; producing calyces in August.

12. J. lanceolata, caule procumbente, subsimplice: foliis patentibus, ovato-subrotundis : 
fructu terminali ; calycibus oblongis, cylindraceis ; apice depresso, piano ; ore con- 
tracto, inciso-dentato. (Tab. xviii.) 
13. J. cordifolia, caule erecto, flexuoso, dichotomo : foliis erectis, concavis, cordatis, cir- 
cumvolutis : fructu terminali axillarique ; calycibus oblongo-ovatis, subplicatis ; ore 
minuto, denticulato. (Tab. xxxii.)
