CampbelTs Islands] FLORA ANTARCTICA. 165 



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 pa- 

 tent. 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 imbrica- 

 tis 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. serpyUifolia, 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.
