57. J. barbata, caulc procumbente, simpliciusculo : foliis rotundato-quadratis, tri-quadri- 
fidis ; stipulis lanceolatis, acute bifidis, margine laciniatis: fructu terminali ; caly- 
cibus ovatis ; ore contracto, dentato. (Tab. lxx.) 
58. J. albescens, caule repente, ramoso : foliis valde concavis, propemodum hemisphaericis, 
emarginatis ; stipulis ovato-lanceolatis, obtusis : fructu in ramis brcvibus terminali ; 
calycibus oblongo-ovatis ; ore dentato. (Tab. lxxii. and Suppl. Tab. iv.) 
I am happy to be able to offer a figure of the fructification of this species in the 
supplementary plate above quoted. The calyces are oblongo-ovatc, with a contracted 
mouth, and dentate j situated upon short, lateral branches, and surrounded at the base 
with perichcetial leaves, which scarcely differ from the rest but in being larger. The 
capsule is ovate, splitting into four equal valves. Seeds and spiral filaments deep brown. 
The plant is extremely common on the more elevated Alps of Switzerland, and I met with it, 
bearing capsules, as well upon the Grimsel as upon the Susten, near the limits of perpetual 
snow. It is from the last-mentioned spot that the specimen here figured was gathered. 
(Fig. 1, J. albescens, magn. 6 ; f. 2, portion of the stem, shewing the stipules, magn. 4 ; 
f. 3, seeds and spiral filaments, magn. 1.) 
59. J. reptans, caule repente, stellatim ramoso : foliis superne imbricatis, subquadratis, 
incurvis, acute quadridentatis ; stipulis lato-quadratis, quadridentatis : fructu radi- 
cali; calycibus oblongis, plicatis ; ore dentato. (Tab. lxxv.) 
60. J. trilobata, caule repente, flexuoso, ramoso: foliis superne imbricatis, ovatis, con- 
vexis, obtuse tridentatis ; stipulis lato-subquadratis, crenatis : fructu e parte caulis 
inferiore egrediente ; calycibus oblongis, subacumiuatis ; ore lateraliter fisso. —

61. J. platyphylla, caule procumbente, pinnatim ramoso : foliis intsqualiter bilobis ; lobis 
superioribus rotundato-ovatis, subintegcrrimis ; inferioribus stipulisque ligulatis, 
integerrimis : fructu laterali ; calycibus ovatis, compressis, ore truncato, inciso- 
serrato, hinc longitudinaliter fissis. (Tab. xl. and Suppl. Tab. iii., where the roots 
are represented fastigiate, as described at I ab. xl.)
