Csespites extensi, laxi, luride rufo-bruunei. Caulis erectus, parce ramosus, dorso radiculia fibrillosis purpureis per totam longitudinem instructus, apicibus subcurvatis. Folia latiuscida, concava, patentia, marginibus undulatis, erosis. Stipularum latinise ssepius insequales.

One of the more slender species of the genus, with the leaves short and concave. Colour a dark reddish brown. The leaves are closely imbricated, the lobes uniting by one-fourth of their length. The smaller lobe is folded at the margin, and receives in the sinus thus formed a similar fold of the leaf above ; its inner rounded margin is sharply inciso-dentate. Specifically this is remarkably distinct from any of its congeners, and like the former, is rather an abnormal form.

7. Jungermannia laminigera, Hook. fil. et Wils.; caule csespitoso suberecto ramoso planiusculo, foliis imbricatis patentibus eroso-ciliatis subter lamellatis marginibus lamellisque undulatis ciliato-dentatis, lobo ventrali lanceolato basi bilobo, dorsali semi-cordato, stipulis inajoribus late rotundato-quadratis 4-5- fidis ciliatis, calyce terminali oblongo cornpresso spinuloso ore laciniato ciliato obscure bilobo. Nobis in Lond. Joicm. Bat. v. 3. p. 456. (Tab. CLVI. Kg. IV.)

Hab. Hermite Island, Cape Horn ; on the ground in the woods, abundant.

Ceespites laxi, superne pallide flavo-virescentes, inferne soidide brunnei. Cau/es 1-3 nnc. longi; rands erectis, subfastigiatis. Folia patentia, dorso carinis lamellisve plurimis cristatis infra apicem evanidis ornata, versus apices setosa, marginibus creberrime spinuloso-dentatis. Stipulis majusculse, dorso basi obscure lamellate, segmentis linearibus subobtusis, marginibus recurvis ciliato-dentatis. Calyx oblongus, i-exsertus, pallidus, extus spinulosus, vix lamellatus. Seta uncialis. Capsula cylindracea.

This a good deal resembles the /. lamellata (v. supra), but is more robust though smaller, the lobes of the leaves are more united throughout then - whole length and the stipules are 4-5-fid. It varies much in size, some of our specimens being hardly an inch long.

8. Jungeiuiannia ansata, Hook. fil. et Tayl.; caule graeili laxe caespitoso elongato subramoso, foliis laxe imbricatis planis erectis appressis secundis oblique rotundatis basi decurrentibus integerriinis fuscis. Nobis in Lond. Journ. Bot. v. 3. p. 457. (Tab. CLVI. Fig. VI.)

Hab. Falkland Islands ; amongst moss on the lulls, abundant.

Csespites laxi, inter muscos implexi, pallide brunnei. Caules fiexuosi, graciles, tenues, vix ramosi, Folia submembranacea, integerrima, rotundata, ereeta, cauli appressa, hinc homomalla, margine anteriore obscure recurvo, posteriore decurrente.

In habit resembling the /. colorata, Hook. (v. infra), but the stems are more elongated, and the leaves quite entire and free, not united into opposite pahs at their bases. The same characters distinguish it from the PI. Braunii of Java, which further has heteromallous leaves. The trivial name alludes to the produced lower margin of the rounded leaf forming a handle.
