162 Caspites lati, appressi, plaiii, olivaceo-brumiei. Caules 1-4 una longi, irregulariter pinnati, ramis divaricatis.

Folia basi angusta, concava ; lobo inferiore basi tumido, superiori obtuse angidato arete appresso. Found abundantly in Ireland, and according to Lindenberg in Switzerland ; in the former locality, as in its southern habitat, preferring wet rocks. It may be distinguished from /. 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 on the larger or upper, and by the deflexed perichsetial leaves ; besides these characters we may remark that the perigonia are usually terminal and not upon lateral short branches, and that the angulate portion of the lower lobe is shorter than in /. complanata.

61. Jtjngermannia uvifera, Hook. fil. et Tayl. ; canJe implexo procumbente pinnatim ramoso, foliis imbricatis patentibus integerrirnis, lobo superiore majore convexo late oblongo-rotundato apice recurvo basi rotundato, inferiore superne truncato v. rotundato ovato-oblongo obtuso inferne subtumido apice lobo supe- riori appresso, perigoniis lateralibus filiforinibus sub foliis latentibus, calyce obovato-oblongo valde compresso subcochleariforrni utrinque marginibus acutis subalatis lateribus basi ad medium 4-5 costatis, ore truncato integro.

Hab. Lord Auckland's group ; on the bark of trees, &c, abundant.

CcBspites plamusculi v. tumidi, late extensi, olivaceo-brunnei, implexi. Caules 1-2 unc. longi, crassiusculi, valde ramosi, foliis convexis undique imbricati, apicem versus saepe purpurascentes. Folia subrecivrva, late obovato-rotundata ; lobo superiore nunc deorsum in auxiculam producto, nunc angustiore, lobo inferiore magnitudine superioris, superne eo arete appresso inferne tumido, forma varia, substantia opaca laete sed pallide flavo-brunnea. Innovationes infra folia plurimi, breves, parvi, perigoniis saepe alternantes. Perigoma omnino inter folia occlusa, minuta, filiformia, fohis 8-10 urceolatis arete imbricata. Perichatium e foliis duobus erectis constans, apicibus latis rotundatis, lobo inferiore subinvoluto.

This species is closely allied to the R. pectinate, Nees, but the upper lobes of the leaves are more elongated and the lower are broad at the apex, the perigoma also are shorter. The calyx is here remarkable for the compressed margins being almost winged and the two sides furnished with several elevated costse. The smaller lobe of the leaf is at first very tumid, more appressed when older. (16. Madotheca, Dmnort.)

Hab. Lord Auckland's group ; on trunks of trees in the woods.

Very closely allied to the European /. 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 tips ; the capsule also is split down to the very base into four valves. Montague compares it with M. mibsquarrosa, Nees and Mont., from Juan Fernandez.

Hab. Campbell's Island; on alpine rocks.

The foliage is paler in colour 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.
