Found abundantly in Ireland, aud according to Lindenberg iu Switzerland ; in the former locality, as in its
southern habitat, prefeiTing wet rocks. It may be distinguished from J. complanata, L., by its smaller size, more
convex leaves, thin texture and brown colour, by the lesser lobe being tumid at the base and not sharply reflected ou
the larger or upper, and by the deflexcd perichætial leaves ; besides these characters we may remark that the peri-
gouia are usually terminal aud not upon lateral short branches, and that the augniate portion of the lower lobe is
shorter than in J. comp~

This species is closely allied to the R. pedinata, Nees, but the upper lobes of the leaves are more elongated
and the lower are broad at the apex, the perigonia also are shorter. The calyx is here remarkable for the compressed
margins being almost winged and the two sides furnished with several elevated costæ. The smaller lobe of the
leaf is at first very tumid, more appressed when older.

Very closely allied to the European J. platyphylla, differing chiefly in the less decidedly pinnate ramification,
in the more distant branches, in the frequent toothing of the lower lobe (not shown in Montague’s figure), and in the
plane margins of the stipules, which are recurved only at the tip s ; the capsule also is split down to the very base
into four valves. Montague compares it with M. subsfjuarrosa, Nees and Mont., from Juan Fernandez.

The foliage is paler in colom- and more lax than in the specimens figured in the ‘ Musci Exotici.’ It is also a
native of Tasmania, from whence we have specimens with fully formed calyces.

These specimens vaiy much in colour, in general they are of a richer brovm, and less olivaceous than in the
figm-e quoted, at other times they are nearly black.

The perichætial leaves in tliis species are three, closely embracing the base of the calyx ; the two lateral entire,
obovate, having a strap-shaped acute cm-ved inner lobe with reflexed sides; the thii-d or stipular lobe is oblong,
deeply dirided into recmwed linear segments, whose margins are imeven Imt not toothed. Calyx cyhndncal and
smooth for ) way up, then ovate-rotundate, exserted, laciniated ; in the young state it appears terminated by a short
tube.
This species may be known from aE others by the minute, divergent am-ioles below the leaves, and more par-
ticulm-ly by the plicate calyx. Montagne compares it with F. yracilü, noiulosa and mterjrhtipula, and adds that besides
the difference m the caljx, the fii'st of these has the involucral leaves serrated, and in the two others the stipules are
entire.

A beautiful little species and one of the smaUest that is known of this subgenus ; as in / . clavigera the lobes
of the stipules are often replaced by club-shaped aimeles.

The present species bears imicli general resemblance to J. lohulata. Hook., differing from it m the smaller size,
the narrow base of the calyx, which is of a ditferent and less trigonous form, being wider above, and in the acute
or apiculate leaves of the pcricliætium. It is as smaU as the previous species.
