Folklands, etc.] CRYPTOGAMIA ANTARCTICA. 123 
Haz. Hermite Island, Cape Horn; from the sea to the mountain-tops. Falkland Islands; on the 
hills. Kerguelen's Land; particularly abundant on the ground, on the hills. 
Also found in New Holland, Tasmania, and New Zealand, Lord Auckland's group, the Cape of Good Hope, 
and Juan Fernandez. In the Falkland Islands it forms large black patches on the alpine rocks, resembling an 
Andreea. 
21. JUNGERMANNIA byssacea, Roth ; Cat. Bot. vol. 2. p.158. Engl. Bot. t. 2463. 
Has. Falkland Islands; amongst mosses on the hills. 
22. JUNGERMANNIA bicuspidata, Linn.; Hook. Brit. Jung. V. 11. Engl. Bot. t. 2239. 
Has. Falkland Islands; on moist rocks. 
One of the, comparatively speaking, few. Hepatice, which, according to the modern limitation of species, is 
acknowledged to be a cosmopolite. 
23. JUNGERMANNIA rigens, Hook. fil et Tayl.; minima, laxe cellulosa, ceespitosa, caule prostrato sub- 
pinnatim ramoso, ramis erectis, foliis laxe imbricatis suberectis concavis late oblongis bifidis, segmentis 
incurvis late subulatis integerrimis, stipulis ovato-rotundatis concavis bifidis segmentis late subulatis integer- 
rimis. Nobis iz Lond. Journ. Bot. vol. 3. p.461. (Tas. CLVII. Fig. III). 
Has. Falkland Islands ; on moist maritime rocks. 
Ceespites parvi, pallide olivaceo-flavescentes. Caules 2-3 lin. longi, carnosiusculi, simplices v. ramosi. Folia 
sursum gradatim minora, imbricata, tumida, hine caulis submoniliformis. Stipule pro planta ample, foliis consimi- 
les, ad medium v. supra medium bifide. 
Allied to the British J. Francisci, Hook., but more minute, the leaves more concave, and the stipules of a very 
different form.

24. JUNGERMANNIA tubulata, Hook. fil. et Tayl.; parvula, caule laxe ceespitoso procumbente ramoso, 
foliis laxis suberectis oblongis bifidis segmentis acutis acuminatisve, calyce terminali anguste lineari-elongata 
tubulata, basi oblongo, ore plicato minutissime denticulato, foliis perichetialibus segmentis lanceolatis inte- 
gerrimis. Nobis ¿z Lond. Journ. Bot. vol. 3. p. 463. (Tas. CLVII. Fig. VI). 
Has. Falkland Islands ; on moist rocks near the sea. 
Caules graciles, laxe ceespitosi, simpliciusculi v. ramosi, vix 4 unc. longi, scepissime ramulis flagelliformibus 
nudis aucti, (ut in J. bicuspidata, L.), pallide virescentes. Folia erecta, pallida, pellucida, basi concava, in segmentis 
duobus lanceolatis apice subulatis divisa, sinu angusto acuto.  Calyces conspicui, albidi, elongati, superne subinflati 
et plicati, ore minutissime denticulato. Folia perichztialia erecta; segmentis angustis, integerrimis. Capsula oblonga. 
Spore numerosissime, luteo-brunnez, subangulatze. — E/aferes e helice duplici constantes. 
So very near the European J. dicuspidata, as to be hardly distinguishable from it specifically : the capsules are 
however shorter, the perichzetial leaves entire, the calyx longer, and the areole of the foliage smaller. The calyces 
are always terminal, whereas in J. bicuspidata they are more frequently lateral.
