164 FLORA ANTAECTICA. [Auckland and 



ramis brevibus, foliis distichis imbricatis patentibus concavis late rotuiidatis apice recurvis superioribus late 

 ovatis grosse dentatis, aurieulis interdurn nullis superioribus nunc bifidis seginento exteriore clavato interiore 

 subulato, stipulis bi-quadripartitis. (Tab. LXVI. Tig. II.) 



Hab. Lord Auckland's group ; rocks on the mountains. 



Ceespites 2-3 unc. lati, planiusculi, rupibus appressi, intertexti, nigrescentes, nunc pallidiores, innovationibus 

 laete purpureis. Canles sub 2 unc. longi, interdurn elongati, ramis plerumque brevibus. Folia tenerrima, valde pel- 

 lucida, areolis majusculis, inferiora integerrima, ssepe lobulo intus aucta. Stipula concavse, profunde partitas, non- 

 nullis v. omnibus clavatis. 



This is a very beautiful microscopic object, and though allied to /. clavigera is very distinct from it. The lower 

 leaves are sometimes nearly reniform, with no auricle whatever, but the most remarkable differential character lies in 

 the very lax reticulation of its cells

69. Jungermannia aterrima, Hook. fil. et Tayl.j pusilla, caule implexo procumbente vage ramoso, foliis 

 imbricatis patentibus convexis rotundato-oblongis integerrirnis marginibus recurvis, aurieulis late oblongo- 

 pyriforrnibus inflatis, stipulis minutis ovatis bipartitis segmeutis lanceolatis basi extus unidentatis, perigoniis 

 rotundatis, foliis perichsetialibus integerrirnis incurvis. (Tab. LXVI. Tig. III.) 



Hab. Lord Auckland's group ; on alpine rocks, mixed with Andrecea and other mosses. 



Ceespites nigri, apicibus nitidis rarius purpurascentibus ; ramis subsolitariis. Folia rotundata v. late et oblique 

 ovata. Stipula bipartite, integrae v. utrinque dente majusculo extus aucto et hinc quadrifidfe. Planta plerumque 

 monoica. Perigonia breviter pedunculata, arete imbricata, rotundata, superne longitudinaliter sidcata, marginibus 

 foliorum valde incurvis. Periclicetii foKia tria, secunda, valde concava, corpora tria rotundata referentes. 



This has some points of affinity with the /. fragilifoUa, Tayl., a species lately observed in Ireland and Swit- 

 zerland, which is equally minute but not so uniformly black and sliining, and has the leaves less densely cellular, and 

 the perichfetial ones dentate.

 tial leaf; magnified. 



70. Jtjxgermannia congesta, Hook. fil. et Tayl.; csespitosa, caule procumbente ramoso, foliis imbri- 

 catis patentibus hitegerrimis late ovatis rotmidatisve subapiculatis, auricula inflata oblongo-pyriformi, stipulis 

 minutis ovato-rotundatis bifidis integerrirnis, foliis perichaetialibus oblongis apiculatis integerrirnis albidis. 



Hab. Lord Auckland's group ; on rocks and on the bark of trees. 



CcBspites extensi, sub 2 unc. lati, pahide flavo-brunnei. Caules gracdes, sub 2 unciales, pinnatim ramosi ; ramis 

 erecto-patentibus, ssepe ascendentibus v. sursum curvatis. Folia valde convexa, plerumque apiculata, 'auricula caule 

 remota infra marginem foKi extensa. Stipula integerrirnae, caule vix latiores, apicem versus bifida, segmentis acutis. 

 Folia perichcetialia erecta, integerrima, acuminata, duobus lateralibus oblongis lobulo inferiore margine inflexo, 

 stipulari in segmenta duo lanceolata apiculata integerrima fissa. 



Very similar to the /. ptgehantha, Mont., but the whole plant much smaller, the auricles occupy a different 

 position, and the perichfetial leaves are of a different form. The barren perichaetia which have roimded summits, are 

 probably modified in the perfect plant. Prom J. aterrima, to which it is in some respects allied, it may be known by 

 the larger size, pale colour, acute perichaetial leaves, and, above all, by the entire stipules.
