424 FLORA ANTARCTICA. \Fuegia, the 



einarginatis, perichaetialibus majoribus imbricatis in capituluni clavatum congestis. Nobis in Lond. Joum. of 

 Bot. vol. 5. p. 258. 



Hab. Foul Haven, Kerguelen's Land ; on clay banks, at an elevation of 600 ft. 



Caespites extensi, 1-2 unc. lati, valde incouspicui. Caules atri, diametro setae equinae, erassiusculi, subnudi, basi 

 hie illic cieatricati, superne foliis parvis tumidis appressis rernotis quasi nodosi, fertiles apices versus foliosi, e foliis 

 perichaetialibus gradatim majoribus arcteque imbricatis clavati. Folia late quadrata, supra medium apicibusque 

 erosis pallida. 



A remarkably distinct little species, forming very obscure black patches on the ground. Stems why when dry, 

 and loosely tufted ; those of the perichaetium paler and olive-brown, having their apices twice as broad as any other 

 parts of the shoot. Perichaetial leaves more imbricated, rounder, broader, and more concave than the cauline, 

 enclosing a pair of minute whitish connivent seariose scales, but without any trace of calyptra or barren pistilla.

 Hab. Staten Land, Menzies. Herrnite Island, Cape Horn, in dense woods abundant. 



This beautiful species is apparently peculiar to the southern extreme of the American continent. 



4. Jungermannia leucopJ/ylla, Lehm. MS. Gottsche, Lind. et Nees ; St/n. Hep. p. 17. 

 Hab. Strait of Magalhaens; Commerson (in Hb. Reg. Berol.). 



5. Jungermannia splachnophylla, Hook. fil. et Tayl. ; caule crasso subdisperso procumbente simplici 

 recurvo e foliis complicatis densissiineque imbricatis squamoso dorso fibrillis squamisque densissime obsito, 

 foliis erecto-patentibus undulato-complicatis carnosis marginibus sub-erosis, lobo ventrali oblongo-ovato, 

 dorsali subaequali semi-ovato, ala lineari undulata. Nobis in Lond. Joum. Bot. vol. iii. p. 455. (Tab. CLVI. 

 Kg. II.) 



Hab. Herrnite Island, Cape Horn; on the ground amongst underwood, alt. 800-1000 ft., and thence 

 to the hill-tops. 



Caules 2-unc. longi, crassi, terra? appressi, sub j-une. lati, dorso densissime filamentosi, substuposi. Folia sor- 

 dide alba, densissime imbricata et comphcata, carnosa et aquosa, fragilissima, marginibus hinc saepissime erosis, 

 paulo incurvis, basi sese arete amplectentia. 



A very singular plant, differhig in its carnose texture from all the previously described species. The leaves are 

 so thick, brittle, and watery as to be crushed to pieces readily between the finger and thumb, whence the analysis of 

 the dried specimens is extremely difficult.

 portion of stem : — magnified. 



6. Jungermannia pachyla, Hook. fil. et Tayl. ; eaule caespitoso erecto subramoso ramisque apice incur- 

 vis anguste linearibus, foliis inflatis dense imbricatis erecto-patentibus, lobis ovato-oblongis acuminatis apicibus 

 incurvis, dorsali integerrimo dorso convexo, ventrali undulato horizontal margine anteriore basi dentato, 

 ala anguste lineari, stipulis majoribus late ovato-quadratis bifidis segmentis lanceolatis apice incisis. Nobi: 

 in Loud. Joum. Bot. vol. iii. p. 456. (Tab. CLVI. Fig. III.) 



Hab. Herrnite Island, Cape Horn ; on the bare ground in wet places.
