Moist alpine spots, among rocks, frequent, (i. in more elevated

state of this plant is very handsome and easily recognized by the above
characters and its numerous almost lezflessflagellce. Abortivefructifi-
cation has been found by Mr. Wilson at Killarney, on the 2 first varie-
ties. Perfect fruit I have only seen on continental specimens. It is
dorsal in its origin, as is the case with J. viticulosa, revtans y Trichomanis,&c.
** Stipules as large as the leaves or nearly so, and easily confounded
with them.

bearing the perichsetial leaves. Sw. Fl. Lid. Occ. p. 1855.—/3.

mountains. Ft. -—-.—Habit almost that of an Andrcea, 3—5 or 6 inches
tall. Calyx, which itself seems formed of united perichcetial leaves, con-
cealed by other leaves which arise from it. Setce very short. Thefruit
is exceedingly scarce on European specimens. The West Indian state
of the plant, larger and with spreading segments to the leaves, is not
unfrequently found in fr. in Jamaica.
57.J.juldc8a, Linn, (silvery alpine Jungermannid) ; stem nearly
erect branched filiform, leaves and stipules ovate closely imbricated
erect deeply and acutely bifid, those of the perichsetium
quadripartite the segments lanceolate acuminate subserrated
erect, fruit terminal, perianth oblong plicated upwards, the
mouth open toothed. Linn. Sp. PI. p. 1601. E. Bot. t. 1024.

Abundant on the ground and on rocks, in the high mountains. Fr.
June, July.—This is altogether an alpine species, of small size, but
growing in very dense compact tufts, often rendered conspicuous by a
silvery white hue which appears to be occasioned by a kind of bloom on
their surface.
58. J. laxifolia, Hook, (lax-leaved Jungermannid); stem erect
nearly simple filiform, leaves and stipules remote erecto-patent
ovate subcarinate acutely bifid with acute erect segments, those
of the perichsetium similar, fruit terminal, perianth oblong sub-
plicate, the mouth contracted toothed. Hook. Br. Jung. t. 59.

Mountain rivulet near Bantry, Miss Hutchins , and in a stream near
Castle-Kelly mountain, Wicklow, Dr. Taylor. Fr. Apr.— This, with
much of the habit of J.julacea, has lax foliage, of a pale green colour,
with large cellules and different pcrichcetial leaves.
