1 . JCYGEEMA>-YIA stygia, Hook. fil. et Tayl. ; perpusilla, caule erecto laxe cæspitoso ramoso, foliis
erectis subimbricatis appressis obovatis obtusis integris v. emarginatis, pericbætüs rotmidatis caule duplo
latioribus. (Tab. LXII. Fig. IT.)
H a b . Campbell’s Island; on rocks on tbe liills, groiring amongst otber NepaÜeæ and Mosses.
Caules 2-3 lin. longi, crassiusculi, superne fusco- v. atro-purpurei, inferne fusco-olivacei vage ramosi; ramis
divancatis. Folia minima, subsecunda, altema, vix imbricata, obovata v. oblonga, apices vei-sus obtusos late emarginata,
segmentis obtusis, rarius integra, margine superiore interdum scariosa. Perici,ætia subrotundo, folüs imbri-
catis, latiusculis, ad apices albidos plerumque scariosis.
A very inconspicuous bttle species, approaching J. oottemmfa (Lightf.), of which it is probably ti e representative
in these islands. Tie leaves are. however, more distant, never bifid at the apex, ti e stems slenderer and
the perichætia sessüe and round. Its colour is like Ggmu. adustum, Nees, a German plant, with short and
simpler steins.

2. JuYTGEEMAA-ATA aeinocifolia, Hook. fil. etTayl.; atro-fusca, caubbus erectis cæspitosis parce ramosis,
fobis secundis ante imbricatis erectis acinaciformibus integerrimis apice rotundatis demum scariosis concavis
atro-purpiireis. (Tab. LXII. Fig. T.)
* The bberal manner m which the most eminent Naturabsts in each department of Crjptogamic Botany have
afforded tbeir cooperation, has removed the diffidence I should otherwise have felt in puhbshiug this difficult portion
of the Antarctic Flora. To Dr. Taylor’s extensive knowledge and keen discrimination I owe the diagnoses of the
Eepaticm and Liclienes. The large amount of Jungennanma which were cobected, and tbe entangled manner in
which they debght to grow, rendered tbeir separation a task demanding no ordinary patience and skffl. Further,
the microscopic investigation of eighty different species and a much greater number of specimens, entabed upon that
gentleman and myself an amount of lahonr which we would fain hope has resulted in the correct determination of a
coUection so unexpectedly novel and interesting. After a thorough examination by Dr. Taylor, the specimens have
passed twice under my own eyes, preparatoiy to the completion of the descriptions and the drawings, which latter
have been further revised by Mr. Fitch when transferring them to the stone; this severe scrutiny wib. it is to be
trusted, reduce the errors into which I should otherwise personaby have foben, to a veiy smab number.
Amidst so many new species it is not to be wondered that some are advanced with hesitation. In a tribe of
plants so minute, a casual resemblance or a sbght variation may often lead (without reference to the microscope) on
the one hand to a umon of what are not the same, and on the other to a multipbcation of species. The difficulty of
holding a middle course between these extremes is acknowledged. Our plan, when investigating the plants of new
countries, so remote from any whose productions are explored, has been, to consider tangible characters, though
often sbght, as specific differences ; at the same time stating the amount of difference, and hoping that future observers
may obtain such materials as wbl either unite these with the plants of other lands, or tend stib further to
prove them distinct.
H ab. CampbeU’s Island ; on rocks near tbe hül-tops, growing amongst mosses, &c.
Cæspites liiride atro-pm-pm-ei, vix 1 unc. alti, supra muscos ciati. Caules sæpius cui-vati, anni præteriti nunc
ad apices innovationibus binis instriicti. FoUa ita imbricata et secimda ut caulis superne profimde canaliculata ap-
pareat, opaca, aciiiacifonnia, margine posteriore lente recurva, anteriore convexa.
A larger plant tlian tbe 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. I t is perhaps more nearly aUied to th e /, lutescens, Gottsche, but its leaves are broadly
rounded, of a thinner textui-e, the shoots pale lemon-coloui*, the whole plant of a different habit, and further, tlie
latter is fuiiiished with stipules.

3. J u n g e rm a n n ia ochrophylla, Hook. fil. et Tayl.; pallide viridis^ caule suberecto v. decumbente
parce ramoso, foliis disticliis laxe imbricatis erecto-patentibus late obovatis v. subquadratis breviter bifidis
segmentis obtusis concavis, stipulis valde inconspicuis v. nullis. (T a b . LXII. Fig. VI.)
H a b . Lord Auckland’s group; amongst mosses on rocks at the tops of the liiUs, altitude 1200 feet.
Laxe cæspitosa. Cæspites paUide idresccntes, 1 mic. lati et ultra. Caules subunciales, superne subincrassati,
irregulariter piuuatim ramosi. Folia semiamplexicauUa, imbricata, patentia, subdivaricata, obovata, basi angusta,
concava, bifida, sinu brevi, segmentis longitudine vix F folii obtusis. Stipulæ dum adsint minimæ, oblongæ,
apicibus vix emarginatis.
This has more the appearance of the European / . minuta than of any of its congeners, but the leaves are uot so
abruptly truncate, the notch at their summits is much narrower and theii* sides more rounded. I t is a more conspicuous
plant than either of the two preceding, of a looser textm-e and paler colom*, and has patent leaves. From
J. pei'igonialis, 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.

4. JuNGERMANNiA yjmyowte//«. Hook. fil. etTayl.; pusilla, caule cæspitoso erecto subramoso, foliis
approximatis suberectis secundis obovatis v. ovato-rotundatis inæqualiter bifidis subobtusis basi seini-am-
plcxicaulibus marginibus integerrimis, perigoniis ovato-oblongis, foliis perigonialibus arcte imbricatis sub-
integris valde concavis basi ventricosis saccatisve. (Tab. LXII. Fig. VII.)
IL yb. Lord Auckland’s gi'oup ; on rocks, at the tops of the hills.
Cæspites densi, luride brimnei, 2-3 unc. diametro. Caules graciles, intertexti, sub F une. longi, crassiusculi.
Folia laxe imbricata, subsecunda, curvata, breviter bifida, sinu obtuso, segmento inferiore pleiumque majore. Pm -
gonia plurima, terminalia v. ramulis ultimis lateralia, basi subampullacea v. in sacculum producta, apicibus brevibus,
rarius emarginatis, mmc bifidis.
No calyces have been observed upon this plant, which is so nearly allied to the / . Funckii, Mohi*, that they
miglit easily be confoimded ; the latter differing in its short stems and more closely imbricated leaves, which are,
as well as those of the convolute pcrigonia, acutely bifid ; the segments of aU are acute. I t also a good deal resembles
J. stygia, nobis, though the plant is larger and the leaves have a vei*y different dii*ection.
