Falklands, etc.] 13. Juxgerhannia spJialera, Hook. fil. et Tayl.; caule laxe ceespitoso erecto basi ramoso apice incurvo, foliis vix imbricatis subhorizontaliter patentibus secunclis siccitate suberectis late oblique ovato-rotundatis acutis, apice inaequaliter bifido v. bidentato, margine superiore incurvo integerrimo, inferiore plauiusculo dentato lase celluloso. Nobis in Land. Journ. Bot. vol 3. p. 458. (Tab.CLVI. Fig. VIII.)

Hab. Hermite Island, Cape Horn ; growing amongst mosses in the woods.

Caespites laxi, pallide olivacei. Caules 1-2 unc. longi, raro in ramos 2-3 erectos divisi. Rami cornpressi, recti v. curvati, apicibus rotundatis. Folia remotiuscnla, madore patentia, sed secunda, apicibus subrecurvis, basi contracta, margine inferiore grosse irregulariter serrato.

Nearly allied to J. uncialis, but taller, with the leaves more remote, less Imbricated and secund, more loosely cellular and not so strongly dentate. When moistened the differences are more apparent, the leaves in particular of /. sphalera being distinctly narrowed at the base,

14. Jtjxgerhaxxia uncialis, Hook. fil. et Tayl. ; caule breviusculo csespitoso suberecto v. prostrato et ascendente ramoso, foliis imbricatis erecto-patentibus concavis late ovatis acutis argute irregulariter ciliato-dentatis sublaxe cellulosis, margine inferiore subrecurvo, calyce majusculo terminali compresso late obovato, ore oblique subrotundato dentato-ciliato. Nobis in Lond. Journ. Bot. vol. 3. p. 459. (Tab. CLVI. Fig. VII).

Hab. Hermite Island, Cape Horn ; on damp rocks and the trunks of trees.

Caespites late extensi, pallide flavo-virescentes. Caules vix 1 unc. longi, subprostrati, rarius erecti, vage ramosi, ramis fructiferis subfastigiatis. Folia vix decurrentia, perichaetialia calyce A breviora. Calyx obovato-cuneatus, conipressus, ore obtuse rotundato, oblique iisso, senadato. Capmla oblongo-spheerica, vix exserta. Perigonia in spicas breves secus ramos disposita.

In habit the present approaches the African P. sarmeiitosa, Lindb., but in character it is more nearly allied to our Tasmanian /. aculeata. The former, whose fructification is unknown, has larger and more rounded leaves. The /. aculeata is a much larger plant ; its leaves have a narrower base, and their superior margin is recurved with a broader fold, the denticulation is coarser, and calyx shorter, being scarcely exserted beyond the perichsetial leaves; above all, the cellulation of the J. uncialis is much coarser though belonging to a smaller plant.

Hab. Strait of Magalhaens ; D' Urville.

A very different plant from any collected by the Antarctic Expedition.

16. Jungeiijiannia rninutula, Hook. fil. et Tayl. ; csespitosa, caule brevissimo erecto parce ramoso, foliis imbricatis erectis appressis obovato-rotundatis convexiusculis, margine anteriore subdecurrente posteriore recurvo, supremis majoribus denticulatis. Nobis in Bond. Journ. Bot. vol. 3. p. 459. (Tab. CLVII. Fig. I). Hab. Kerguelen's Land ; on the ground and on moist rocks.

Csespites late extensi, atro-virides. Caules erecti, crassiusculi. Rami primarii vix a unc. longi. Folia inferiora minuta, subintegerrhna, caide vix latiora, gradatim majora, superiora arctius imbricata, in capitulum compressum dilatatum congesta, superiora creuato-denticulata, omnia crassa, obscure cellulosa ; cellulis parvis, opacis, marginalibus conspicuis.
