Falklands, ete.) CRYPTOGAMIA ANTARCTICA. 125 
Tayl. (J. socia. var., Gottsche, Lind. et Nees), differing in the paler green colour of the young shoots, in the 
more delicate foliage, smaller areolee, deeper emargination and clasping leaves. 
Prare CLVII. Fig. V.— 1, plants of the natural size; 2, stipule; 3, leaf :—both magnified. 
28. JUNGERMANNIA austrigena, Hook. fil. et Tayl.; laxe ceespitosa, caule elongato ascendente sub- 
ramoso, surculis incurvis, foliis imbricatis subsecundis erecto-patentibus rotundatis convexis integerrimis 
marginibus recurvis pericheetialibus rotundatis, stipulis majoribus rotundatis, marginibus reflexis integerri- 
mis bidentatisve, calyce terminali oblongo compresso ore subintegro trigono. J. austrigena et J. cavispina. 
. Nobis in Lond. Journ. Bot. vol. 3. p. 463 et 466. (Tas. CLVII. Fig. VIT. and Tas. CLVIII. Fig. V). 
Has. Hermite Island, Cape Horn; moist banks in woods (fruit). Falkland Islands, along with J. 
humectata. 
Ceespites laxi, lati, pallide flavidi, virides v. atro-brunnei. Caules 2-3 unc. longi, vage ramosi, flexuosi, cras- 
siusculi. Folia arcte imbricata, subopposita, antice decurrentia , siccitate plerumque crispata, recurva; madore sub- 
erecta, appressa, marginibus plus minusve recurvis.  S/ipule rotundate, basi utrinque decurrentes, integerrime v. 
apice bidentate, marginibus valde deflexis porrectis, intra margines posticos foliorum verticaliter compresse. Calyx 
majusculus, oblongus, latiusculus, trigonus. 
A very curious species, and unlike any with which we are acquainted. The habit of the Falkland Island speci- 
mens when dried, is, owing to their having grown in water, so peculiar, that we regarded them at first as a 
different species, which we described as J. cavispina, from the reflexed margins of the closely imbricating stipules, 
giving a grooved appearance to the back of the stem. The calyx is that of a Lophocolea, from which group the 
presence of stipules and the entire leaves remove it. ; 
Puate CLVII. Fig. VII. Falkland Island state, (sub nom. J. cavispine).—1, plant of the natural size ; 2, front, 
and 3, back view of stem and leaf; 4, stem and stipule; 5 and 6, stipules :—magnified. Puare CLVIII. Fig. V. 
(Hermite Island state).—1, plant of the natural size; 2, lateral, 3, back, and 4, front view of stem, leaf, and 
stipule ; 5, stem and stipule; 6 and 7, stipules :—magnified. 
29. JUNGERMANNIA palustris, Hook. fil. et Tayl.; caule elongato disperso flaccido ramoso, foliis laxe 
imbricatis erecto-patentibus tenuissime membranaceis rotundatis valde concavis marginibus incurvis medio 
longitudinaliter undulatis integerrimis, stipulis majoribus ovalibus cymbiformibus integerrimis. Nobis ¿n 
Lond. Journ. Bot. vol. 3. p. 464. (Tas. CLVII. Fig. VIII). 
Has. Hermite Island, Cape Horn; on the borders of an alpine lake, growing in the water. 
Caules inter Muscos aliasque Hepaticas demersas ascendentes, sparsi, 3 unc. longi; ramis erectis, flaccidissimis. 
Folia tumida, varie incurva, medio plerumque plica longitudinali notata. Stipule valde concavee, subimbricatee. 
Allied to the British J. Doniana, and to the J. involutifolia, Mont. (v.infra), but very distinct from both. 
The leaves resemble those of Hypnum cochlearifolium, Schwaegr. 
Prats CLVII. Fig. VIII.—1, plant of the natural size; 2, front view of stem, leaves, and stipules; 3, back 
view of ditto :—magnified. 
30. JUNGERMANNIA involutifolia, Mont. in Gottsche, Nees et Lind. Syn. Hep. p. 81. Voy. au Pole 
Sud, Bot. Crypt. p. 260. 2 
Has. Strait of Magalhaens; on tufts of Hypnum fluitans: M. Hombron. 
The nearest ally to this plant is J. notophylla, nobis.
