Campbell’s Islands] 71. Jungermannia scandens. Frullania scandens, Mont, in Toy. au Pole Sud, Bot. Crypt. 1. 19. f. 2. et in Annal. des Sc. Nat. 1S43, p. 258.

Hab. Lord Auckland's group; on branches of trees (MM. Hombron et Jacquinot).

This species was not found during the stay of the Antarctic Expedition in Lord Auckland's group. Monta°-ne compares it with F. Mans, ornithocepkala, and obscura, Nees.

(18. Lejeunia, Lib.)

72. Jungermannia implexieaulis, Hook. fil. et Tayl. ; caulibus cajspitosis suberectis ramosis, foliis laxe imbricatis suberectis patentibus vnlde concavis ovatis obtusis apicibus marginibusque incurvis areolis punctiformibus, lobulis anguste ovatis tuniidis inflexis, stipulis rotundatis caule latioribus apice fissis seg- mentis suberectis.

Has. Campbell's Island; creeping through tufts of mosses in rocky places.

Caules -j-1 unc. longi, inter muscos dispersi v. crespites plus rninusve confertos formautes, olivaceo-vh'ides, vage ramosi, ramis erectis. Folia valde concava, hinc oculo nudo rami moniliformes apparent, subdecurrentia, lobulo cauli proximo, areolis minimis punctiformibus. Stipulce fere orbiculares, primo visu integrse, sed fissse segmentis approximatis v. imbricatis.

Very nearly allied to the /. serpyUifolia, 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 formed of a very compact tissue, the cells of which require a high power to be distinguished, the leaves themselves also are twisted forwards and not patent. The stipules appear undivided, except wheu the segments are forced asunder ; whdst in /. serpyUifolia they diverge and often have a very rounded sinus between them.

73. Jungermannia Mimosa, Hook. fil. et Tayl.; caulibus implexis repentibus ramosis, foliis imbricatis patentibus concavis oblique obovato-oblongis subcurvatis v. acinaciformibus apicibus patentibus recurvis integerrimis, lobulis ovatis involutis, stipulis late ovatis acute bifidis, calyce late elliptico-ovato pentggono ore contracto subtubuloso.

Hab. Lord Auckland's group ; on moist alpine rocks.

Cxspites parvi, fusco-olivacei. Caules sub unc. longi, irregulariter vage ramosi, ascendentes. Folia subincurva, ut in J. serpyUifolia, sed prsesertim apices versus latiora et ad latus curvata, hinc subacinacifonnia, lobulo erecto-patente ; substantia crassiuscida, areolis parvis. Stipiilrr caule vix latiores, apice fissee, segmentis subdistantibus erectis, sinu obtuso. Folia perickalialia late oblongo-rotundata, integra, concava, apicibus recurvis, tertio stipulse conformi sed magis concavo. Periyouia lateralia, spicata ; foliis arete imbricatis, brevibus, rotundatis, tumidis. Calyx basi angustatus, obovatus v. obovato-ellipticus, pentagonus v. sub 5-alatus, ore minuto tubuloso.

The chief points of distinction between this and the .7. aerpyUifolia, Dicks., reside in the denser structure of the leaves, then- tops being recurved"; the larger calyx, which tapers towards the narrower base, and the rounder more concave perichstial leaves. From /. iii/plexicaulis it may be known by the more cellular and planer leaves, their very different direction, and the remote segments of the stipules.

74. Jungermannia primordialis, Hook. fil. et Tayl. ; caulibus exilibus implexis vage ramosis, ramis subpatentibus, foliis laxis suberectis anguste obovatis apicibus rotundatis concavis integerrimis lobo inferiore ovato iuvoluto, stipulis minimis emarginato-bifidis segmentis linearibus subobtusis divaricatis.

Hab. Lord Auckland's group ; on a species of Sticta in the woods.
