Falklands, etc.] FLORA ANTARCTICA. 429 



Hae. 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 

 Andreaea. 



21. Jungermannia byssacea, Eoth ; Cat. Bot. vol. 2. p. 158. Engl. Bot. t, 2463. 

 Hab. Falkland Islands ; amongst mosses on the lulls. 



22. Jungerhannia bicuspidata, Linn. ; Hook. Brit. Jung. 1. 11. Engl. Bot. t. 2239. 



Hab. Falkland Islands ; on moist rocks. 



One of the, comparatively speaking, few Hepaticce, which, according to the modem limitation of species, is 

 acknowledged to be a cosmopolite. 



23. Jungerhannia rigens, Hook, fil et Tayl. ; minima, laxe cellulosa, csespitosa, caule prostrate 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 in Bond. Joum. Bot. vol. 3. p. 461. (Tab. CLVII. Fig. HI). 



Hab. Falkland Islands ; on moist maritime rocks. 



Csespites parvi, pallide olivaceo-flavescentes. Caules 2-3 lin. longi, earnosiusculi, simplices v. ramosi. Folia 

 sursum gradatim minora, imbricata, tumida, hinc caulis subinoniliformis. Stipula pro planta amplee, foliis consimi- 

 les, ad medium v. supra medium bifida?. 



Allied to the British /. Francisci, Hook., but more minute, the leaves more concave, and the stipules of a very 

 different form.

 removed : — magnified. 



24. Juxgermannia tubulata, Hook. fil. et Tayl.; parvula, caule laxe caespitoso procumbente ramoso, 

 foliis laxis suberectis oblongis bifidis segmentis acutis acuminatisve, calyce terminali anguste lineari-elongata 

 tubulata, basi oblongo, ore plicate niinutissime denticulate, foliis perichsetialibus segmentis lanceolatis inte- 

 gerrimis. Nobis in. Bond. Journ. Bot. vol. 3. p. 463. (Tab. CLYII. Fig. VI). 



Hab. Falkland Islands ; on moist rocks near the sea. 



Caules graciles, laxe csespitosi, simpliciusculi v. ramosi, vix ± unc. longi, ssepissime ramulis flagelliformibus 

 nudis aucti, (ut in /. bicuspidata, L.), palhde 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 denticulate. Folia perichcetialia erecta ; segmentis angustis, integerrimis. Capsida oblonga. 

 Sporce nurnerosisshnre, luteo-brunnese, subangulata?. Materes e helice duphci constantes. 



So very near the European J. bicuspidata, as to be hardly distinguishable from it specifically : the capsules are 

 however shorter, the perichsetial leaves entire, the calyx longer, and the areolae of the foliage smaller. The calyces 

 are always terminal, whereas in /. bicuspidata they are more frequently lateral.
