52 CRYPTOGAMIA ANTARCTICA. | Auckland and 
ramis brevibus, foliis distichis imbricatis patentibus concavis late rotundatis apice recurvis superioribus late 
ovatis grosse dentatis, auriculis interdum nullis superioribus nunc bifidis segmento exteriore clavato interiore 
subulato, stipulis bi-quadripartitis. (Tas. LXVI. Fig. II.) 
Has. Lord Auckland's group ; rocks on the mountains. 
Cespites 2-8 unc. lati, planiusculi, rupibus appressi, intertexti, nigrescentes, nunc pallidiores, innovationibus 
leete purpureis. Cawles sub 2 unc. longi, interdum elongati, ramis plerumque brevibus. Folia tenerrima, valde pel- 
lucida, areolis majusculis, inferiora integerrima, seepe lobulo intus aucta. Stipule concave, profunde partite, non- 
nullis v. omnibus clavatis. 
This is a very beautiful microscopic object, and though allied to J. 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.; pusilla, caule implexo procumbente vage ramoso, foliis 
imbricatis patentibus convexis rotundato-oblongis integerrimis marginibus recurvis, auriculis late oblongo- 
pyriformibus inflatis, stipulis minutis ovatis bipartitis segmentis lanceolatis basi extus unidentatis, perigoniis 
rotundatis, foliis perichzetialibus integerrimis incurvis. (Tas. LXVI. Fig. III.) 
Has. Lord Auckland's group; on alpine rocks, mixed with Andreea and other mosses. 
Cespites nigri, apicibus nitidis rarius purpurascentibus; ramis subsolitariis. Folia rotundata v. late et oblique 
ovata. Stipule bipartite, integree v. utrinque dente majusculo extus aucto et hine quadrifide. Planta plerumque 
monoica. „Perigonia breviter pedunculata, arcte imbricata, rotundata, superne longitudinaliter sulcata, marginibus 
foliorum valde incurvis. Perichetii foliia tria, secunda, valde concava, corpora tria rotundata referentes. 
This has some points of affinity with the J. fragilifolia, Tayl., a species lately observed in Ireland and Swit- 
zerland, which is equally minute but not so uniformly black and shining, and has the leaves less densely cellular, and 
the pericheetial ones dentate.

tial leaf ; magnified. 
70. JUNGERMANNIA congesta, Hook. fil. et Tayl.; ceespitosa, caule procumbente ramoso, foliis imbri- 
catis patentibus integerrimis late ovatis rotundatisve subapiculatis, auricula inflata oblongo-pyriformi, stipulis 
minutis ovato-rotundatis bifidis integerrimis, foliis pericheetialibus oblongis apiculatis integerrimis albidis. 
Has. Lord Auckland's group; on rocks and on the bark of trees. 
Cespites extensi, sub 2 unc. lati, pallide flavo-brunnei. Caules graciles, sub 2 unciales, pinnatim ramosi ; ramis 
erecto-patentibus, seepe ascendentibus v. sursum curvatis. Folia valde convexa, plerumque apiculata, auricula caule 
remota infra marginem folii extensa. Stipule integerrime, caule vix latiores, apicem versus bifidze, segmentis acutis. 
Folia perichstialia erecta, integerrima, acuminata, duobus lateralibus oblongis lobulo inferiore margine inflexo, 
stipulari in segmenta duo lanceolata apiculata integerrima fissa. 
Very similar to the J. ptychantha, Mont., but the whole plant much smaller, the auricles occupy a different 
position, and the perichzetial leaves are of a different form. The barren perichzetia which have rounded summits, are 
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 pericheetial leaves, and, above all, by the entire stipules.
