Hab. Campbell's Island; on rocks near the hill-tops, growing amongst mosses, &c.

Cæspites luride atro-purpurei, vix 1 unc. alti, supra muscos elati. Caules sæpius curvati, anni præteriti nunc ad apices innovationibus binis instructi. Folia ita imbricata et secunda ut caulis superne profunde canaliculata appareat, opaca, acinaciformia, margine posteriore lente recurva, anteriore convexa.

A larger plant than the former, or than J. concinnata; of a rigid habit, more sparingly branched and of a fuscous or blackish purple colour, with leaves so densely imbricated all round the stem, that the latter appears terete and grooved down the front. It is perhaps more nearly allied to the J. lutescens, Gottsche, but its leaves are broadly rounded, of a thinner texture, the shoots pale lemon-colour, the whole plant of a different habit, and further, the latter is furnished with stipules.

3. Jungermannia ochrophylla, Hook. fil. et Tayl.; pallide viridis, caule suberecto v. decumbente parce ramoso, foliis distichis laxe imbricatis erecto-patentibus late obovatis v. subquadratis breviter bifidis segmentis obtusis concavis, stipulis valde inconspicuis v. nullis. (Tab. LXII. Fig. VI.)

Hab. Lord Auckland's group; amongst mosses on rocks at the tops of the lulls, altitude 1200 feet.

Laxe cæspitosa. Cæspites pallide virescentes, 1 unc. lati et ultra. Caules subunciales, superne subincrassati, irregulariter pinnatim ramosi. Folia semiamplexicaulia, imbricata, patentia, subdivaricata, obovata, basi angusta, concava, bifida, sinu brevi, segmentis longitudine vix ¼ folii obtusis. Stipulæ dum adsint minimæ, oblongæ, apicibus vix emarginatis.

This has more the appearance of the European J. minuta than of any of its congeners, but the leaves are not so abruptly truncate, the notch at their summits is much narrower and their sides more rounded. It is a more conspicuous plant than either of the two preceding, of a looser texture and paler colour, and has patent leaves. From J. perigonialis, nobis, it may be distinguished by its greater size, paler hue, stout stems and more crowded leaves, which are loosely reticulated and have obtuse segments.

(2. Sarcoscyphus, Corda.)

4. Jungermannia perigonialis, Hook. fil. et Tayl.; pusilla, caule cæspitoso erecto subramoso, foliis approximatis suberectis secundis obovatis v. ovato-rotundatis inæqualiter bifidis subobtusis basi semi-amplexicaulibus marginibus integerrimis, perigoniis ovato-oblongis, foliis perigonialibus arcte imbricatis subintegris valde concavis basi ventricosis saccatisve. (Tab. LXII. Fig. VII.)

Hab. Lord Auckland's group; on rocks, at the tops of the hills.

Cæspites densi, luride brunnei, 2–3 unc. diametro. Caules graciles, intertexti, sub ½ unc. longi, crassiusculi. Folia laxe imbricata, subsecunda, curvata, breviter bifida, sinu obtuso, segmento inferiore plerumque majore. Perigonia plurima, terminalia v. ramulis ultirnis lateralia, basi subampullacea v. in sacculum producta, apicibus brevibus, rarius emarginatis, nunc bifidis.

No calyces have been observed upon this plant, which is so nearly allied to the J. Funckii, Mohr, that they might easily be confounded; the latter differing in its short stems and more closely imbricated leaves, which are, as well as those of the convolute perigonia, acutely bifid; the segments of all are acute. It also a good deal resembles J. stygia, nobis, though the plant is larger and the leaves have a very different direction.
