state of this plant is very handsome and easily recognized by the above 

 characters and its numerous almost lezflessflagellce. Abortive fructifi- 

 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 con- 

 founded with them. 



56. J. juniperina, Sw. (Juniper-leaved Jungermannid); stem

 bipartite falcato-secund, fruit terminal, perianth ovate laciniated 

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

/3. Among rocks, on the mountains of Scotland and Ireland. Welsh 

 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. The fruit 

 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 imbri- 

 cated 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.
