ramis brevibus, foliis disticliis imbricatis patentibus concavis late rotundatis apice recurvis superioribus late
ovatis grosse dentatis, anricubs interdum nullis superioribus nunc bifìdis segmento exteriore clavato interiore
subulato, stipubs bi-qiiadripartitis. (T a b . LX V I. Pig. II.)
H a b . Lord Auckland’s group ; rocks on tbe mountains.
Caspites 3 -3 mic. lati, planiusculi, rupibus appressi, intertexti, nifprescentes, nunc paUidiores, innovationibus
læte purpureis. Caules sub 3 unc. longi, interdum elongati, ramis pleimmque brevibus. Folia tenerrima, valde pellucida,
areolis majusculis, inferiora integerrima, sæpe lobulo intus aucta. Stipulæ concavæ, profunde partitæ, non-
nullis v. omnibus clavatis.
This is a veiy beautiful microscopic object, and though allied to J. clavigera is very distinct from it. The lower
leaves are sometimes nearly renifonn, with no auricle whatever, but the most remai-kable differential character lies in
the very lax reticulation of its cells

H a b. Lord Auckland’s group ; on alpine rocks, mixed with Andreoea and other mosses.
Cæspites nigri, apicibus nitidis rarius purpurascentibus ; ramis subsolitariis. Folia rotundata v. late et oblique
ovata. Stipulæ bipartitæ, integræ v. utrinque dente majusculo extus aucto et hinc quadrifidæ. Planta plenunque
monoica. Perigonia breviter pedunculata, arcte imbricata, rotundata, superne longitudinaliter sulcata, marginibus
foliorum valde incurvis. Perichætii fobia tria, secunda, valde concava, corpora tria rotundata referentes.
This has some points of afiìnity ivith the J. fragïlifolia, Tayl., a species lately observed in Ireland and Switzerland,
which is equally minute but not so imiformly black and shining, and has the leaves less densely cellular, and
the perichætial ones dentate.

H ab. Lord Auckland’s gro u p ; on rocks and on th e bark of trees.
Cæspites extensi, sub 2 unc. lati, pallide flavo-brunnei. Caules graciles, sub 3 unciales, pinnatim ramosi ; ramis
erecto-patentibus, sæpe ascendentibus v. sursum curvatis. Folia valde convexa, pleiaunque apiculata, auricula caule
remota infra marginem fohi extensa. Stipulæ integerrimæ, caule vix latiores, apicem versus bifidæ, segmentis acutis.
Folia perichætialia erecta, integerrima, acuminata, duobus lateralibus oblongis lobulo inferiore margine inflexo,
stipulali in segmenta duo lanceolata apiculata integenima fissa.
Veiy similar to the J. ptychantha, Mont., but the whole plant much smaller, the auricles occupy a difierent
position, and the perichætial leaves are of a different form. The barren perichætia which have rounded summits, arc
probably modified in the perfect plant. From J. aterrima, to which it is in some respects allied, it may be known by
the larger size, pale colour, acute perichætial leaves, and, above all, by the entire stipules.

TMs species was not found diu-ing the stay of the Antarctic Expedition in Lord Auckland’s group. Montagne

7 2 . J i r a G E E M A N X 'iA implcxicauUs, Hook. fil. et Tayl. ; caulibus cæspitosis suberectis ramosis, foliis
laxe imbricatis suberectis patentibus valde concavis ovatis obtusis apicibus marginibusque incurvis areolis
punctiformibus, lobulis anguste ovatis tumidis inilexis, stipulis rotundatis caule latioribus apice fissis segmentis
suberectis.
H a b. Campbell’s Island ; creeping througb tufts of mosses in rocky places.
Caules A-1 unc. longi, inter muscos dispersi v. cæspites plus minusve confertos formantes, olivaceo-virides, vage
ramosi, ramis erectis. Folia valde concava. hinc oculo nudo rami moniliformes apparent, subdecnrrentia, lobulo
cauli proximo, areolis minimis punctiformibus. Stipulæ fere orbiculares, primo visu integræ, sed fissæ segmentis
approximatis v. imbricatis.
Very nearly allied to the J. serpyllifolia, Dicks. ; it has. however, a different aspect, owing to the erect leaves,
which are not plane but very concave, and instead of being loosely cellular are fomed of a very compact tissue, the
cells of which requh-e a high power to be distinguisbed. the leaves themselves also are twisted fonvards and not patent.
The stipules appear- undivided, except when the segments are forced asunder ; whilst in J. serpyllifolia they
diverge and often have a very rounded sinus between them.

ore contracto subtubuloso.
H a b . Lord Auckland’s group ; on moist alpine rocks.
Cæspites parri, fusco-olivacei. Caides sub F ime. longi, frregulariter vage ramosi, ascendentes. Folia subincurva,
ut iu J. serpyllifolia, sed præsertim apices versus latiora et ad latus curvata, hinc subacinacifonnia, lobulo erecto-
patente ; substantia crassiuscida, areolis parvis. Stipulæ caule vix latiores, apice fissæ, segmentis subdistantibus
erectis, sinu obtuso. Folia perichætialia late oblongo-rotundata, integra, concava, apicibus reciuwis, tertio stipidæ
conformi sed magis concavo. Ferigonia lateralia, spicata; foliis arcte imbricatis, brertbiis, rotundatis, tumidis.
Calyx basi angustatus, obovatus v. obovato-ellipticus, peutagonus v. sub 5-alatus, ore minuto tubuloso.
The chief points of distinction between this and the J. serpyllifolia, Dicks., reside in the denser structure of
the leaves, theii- tops being recm-ved ; the larger calyx, which tapers towards the narrower base, and the rounder more
concave perichætial leaves. From J. implexicaulis it may be known by the more cellular and planer leaves, their
very difierent dii-cction, and the remote segments of the stipules.
