118 CRYPTOGAMIA ANTARCTICA. | Puegia, the 
emarginatis, perichetialibus majoribus imbricatis in capitulum clavatum congestis. Nobis in Lond. Journ. of 
Bot. vol. 5. p. 258. 
Haz. Foul Haven, Kerguelen's Land ; on clay banks, at an elevation of 600 ft. 
Cespites extensi, 1-2 unc. lati, valde inconspicui. Caules atri, diametro sete equine, crassiusculi, subnudi, bas 
hic illic cicatricati, superne foliis parvis tumidis appressis remotis quasi nodosi, fertiles apices versus foliosi, e foliis 
perichetialibus 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 wiry when dry, 
and loosely tufted ; those of the pericheetium paler and olive-brown, having their apices twice as broad as any other 
parts of the shoot. Pericheetial leaves more imbricated, rounder, broader, and more concave than the cauline, 
enclosing a pair of minute whitish connivent scariose scales, but without any trace of calyptra or barren pistilla.

Has. Staten Land, Menzies. Hermite Island, Cape Horn, in dense woods abundant. 
This beautiful species is apparently peculiar to the southern extreme of the American continent.

Has. Strait of Magalhaens; Commerson (in Hb. Reg. Berol.). 
5. JUNGERMANNIA splachnophylia, Hook. fil. et Tayl.; caule crasso subdisperso procumbente simplici 
recurvo e foliis complicatis densissimeque imbricatis squamoso dorso fibrillis squamisque densissime obsito, 
folis erecto-patentibus undulato-complicatis carnosis marginibus sub-erosis, lobo ventrali oblongo-ovato, 
dorsali subzequali semi-ovato, ala lineari undulata. Nobis in Lond. Journ. Bot. vol. iii. p. 455. (Tas. CLVI. 
Fig. IL.) 
Has. Hermite Island, Cape Horn; on the ground amongst underwood, alt. 800—1000 ft., and thence 
to the hill-tops. 
Caules 2-unc. longi, crassi, terree appressi, sub 2-unc. lati, dorso densissime filamentosi, substuposi. Folia sor- 
dide alba, densissime imbricata et complicata, carnosa et aquosa, fragilissima, marginibus hine seepissime erosis, 
paulo incurvis, basi sese arcte amplectentia. 
A very singular plant, differing 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. ; caule ceespitoso erecto subramoso ramisque apice incur- 
vis anguste linearibus, foliis inflatis dense imbricatis erecto-patentibus, lobis ovato-oblongis acuminatis apicibus 
incurvis, dorsali integerrimo dotso convexo, ventrali undulato horizontali margine anteriore basi dentato, 
ala anguste lineari, stipulis majoribus late ovato-quadratis bifidis segmentis lanceolatis apice incisis. Nobis 
in Lond. Journ. Bot. vol. iii. p. 456. (Tas. CLVI. Fig. HT.) 
Has. Hermite Island, Cape Horn; on the bare ground in wet places
