SYNOPSIS. 
14. J. Sphagni, caule procumbentc, simpliciusculo ; (elongationibus geimniferis solummodo 
stipulatis!) ; foliis orbicularibus : fructu in ramis propriis terminali; calycibus 
oblongis, utrinque attenuatis ; ore contracto, denticulato. (Tab. xxxiii. and 
Suppl. Tab. ii.)

Mr. Lyell found gemmae in August at Stock-gill Force, near Ambleside, and I met 
with them abundantly in April, on mountains bordering on Dartmoor, Devonshire. The 
fructification I have been obliged to figure in the Supplement, where, at tab. ii. fig. 1. is a 
gemmiferous plant, magn. 6 ; f. 2, extremity of the same, magn. 4; f. 3, gemma, magn. 2 j 
f. 4, the same, magn. 1 ; f. 5, portion of a stem with the female fructification, magn. 6; f. 6, 
proper stalk to the fructification, with the perichcetial leaves and calyx, magn. 4; f. 7, outer 
perichretial leaf-, f. f. 8, 9, inner ditto, magn. 3 ; f. 10, a spiral filament, and f. 11, the 
seeds, both magn. 1. 
Wahlenberg quotes, under J. Sphagni, the J. scalaris of Schmidel's Diss. Jung., in 
which he is probably correct; for the gemmae of that figure correspond sufficiently well 
with our plant. The Swedish author, however, appears to me to have confounded 
with this the J. Taylori of this work, with which a part of his description aptly agrees, 
" valde mollis vel spongiosa, e reticulo laxiore facta,” which is by no means the case with 
J. Sphagni. 
15. J.crenulata, caule procumbente, ramoso: foliis rotundatis, marginatis : fructu ter- 
minal! ; calycibus obovatis, coinpressis, longitudinaliter quadraiigularibus ; ore con- 
tracto, dentato. (Tab. xxxvii.) 
This is plentiful on Burgh Common, near Yarmouth ; and Mr. Lyell finds a small but 
elegant state of the plant at Kinnordy, bearing calyces in August. The male fructification 
resembles that of J. scalaris. It is figured in Suppl. tab. i. 
16. J. spharocarpa, caule ascendente, siinplice : foliis orbiculatis : fructu terminali ; caly- 
cibus oblongo-ovatis, cylindraceis, quadrifidis (capsula sphaerica). (Tab. lxxiv.) 
17. J.hyalina, caule ascendente, flexuoso, dicliotomo : foliis rotundatis, subundulatis : 
Iructu terminali ; calycibus ovatis, angulatis ; ore contracto, quadridentato. 
(Tab. lxiii.) 
18. J. compressa, caule erecto, diviso : foliis orbicularibus, summis reuiformibus, appressis, 
(stipulis in innovationibus solummodo :) fructu terminali ; calycibus foliis immersis, 
oblongis, carnosis ; ore aperto, quadridentato. (Tab. lviii.) 
Plentiful in Switzerland, particularly in the valley of Guttanen, near the Grimsel. 
x x Foliis emarginatis vel bifidis, segmentis ccqualibus. 
19. J. emarginata, caule erecto ramoso : foliis laxe imbricatis, patentibus, obcordatis, emar- 
ginatis : fructu terminali ; calycibus ovatis, dentatis, foliis immersis. (Tab. xxvii.)
