are no flagelliform shoots, and from the irregular number of 
the minute teeth of the leaves, this species can scarcely be 
referred to Herpetium of Nees, 
24. J. madida, n. sp. ; caule cespitoso erecto-ramoso, ramis 
erectis fastigiatis, foliis laxé imbricatis patentibus amplexi- 
caulibus concavis ovato-rotundatis bifidis, segmentis acutis 
incurvis subintegerrimis, stipulis majoribus laté ovatis bifidis 
subintegerrimis, calyce cylindraceo subincurvo apice den- 
tato. 
Has. Hermite Island, Cape Horn. 
Tufts loose, several inches wide, dull green when growing 
in water, rufescent in dry situations. Stems 2 inches high. 
Leaves scarcely imbricated, bifid for one-third of their 
length, a few of them exhibiting one or at most two minute 
teeth on the posterior margin; their structure is minutely 
cellular. The stipules are nearly as large as the leaves, round, 
bifid, the segments subdentate. Calyx long, rather acumi- 
nated. Capsule cylindrical. 
This species is larger and greener when growing in water, 
the leaves are more entire in dry situations. It is closely 
allied to J. serrulata (Swartz), differing by the less imbricated 
leaves, whose cells are much more minute, by the few serra- 
tures of the margins of the leaves, by the stipules and leaves 
being shorter, and by the more elongated calyx. 
25. J. equata, n. sp.; caule implexo procumbente subra- 
moso flexuoso, foliis imbricatis erectis oppositis rotundatis, 
margine incurvis integerrimis, basi connatis, stipulà ovata 
bifidà conjunctis. 
Haz. Hermite Island, Cape Horn. 
Patches small, growing among mosses, reddish-brown. 
Stems about one inch long, variously but sparingly branched, 
bent back. Leaves closely imbricated, oblongo-rotundate, 
Somewhat convex and tumid when moist from their margins 
ming incurved; they are exactly opposite, being slightly 
Connected in front at the base, but joined together behind by 
the intervention of the stipule, which is ovate and bifid with 
‘two subulato-setaceous short segments,
