438 52. Jungermannia grisea, Nobis in Fl. Antarct. Pt. 1. p. 154. t. lxiv. f. 8.

Var. Pylaxa; caule ramoso flexuoso, foliis laxius insertis subremotis alternantibus. (Tab. CLX. Fig. IV.)

Hab. Falkland Islands ; on clay banks near the sea. Var. /3, in similar situations. Also a native of Lord Auckland's group.

Plate CLX. Mg. IV. — 1, plant of the natural size ; 2, stem and leaves ; 3 and 4, leaves ; 5 and 6, stipules : — magnified.

53. Jungermannia reclinans, Hook. fil. et Tayl.; caule prostrato implexo ramoso, foliis imbricatis patentibus siccitate explanatis madore secundis e basi lata ovato-rotundatis integerrimis apiee rotundatis v. obscure retusis, stipubs 2-4-partitis, segmentis setaceis intermediis elongatis. Nobis in Load. Journ. Bot. vol. iii. p. 470. (Tab. CLLX. Pig. I).

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

Ccespites laxe intertexti, pallide flavo-olivacei, inter Muscos Hepatica-sque alias repentes. Caules supini, vix A unc. longi, parce ramosi. Folia margine superiore sursum producto plerumque trilobo, rarius bdobo, lobis latis obtusis, folia nunc integra. Stipules basi angustatse, quadrataa, bipartitse, segmentis plerumque uni-dentatis omnibus setaceis articulatis incurvis.

With much affinity to the /. multipenna of Lord Auckland's group ; but the upper margin of the leaf is not so gibbous or produced upwards, the stipules have the inner segments straight or recurved, but not refiexed, and much more slender.

Plate CLIX. Fig. I.— 1, plant of the natural size ; 2, stem and leaf; 3, stipule ; 4, perichaetium and calyx :— magnified.

54. Jungermannia secundifolia, Hook. fil. et Tayl.; parvula, caule subcaespitoso procumbente sub-ramoso, foliis imbricatis erectis secundis oblongis emarginato-bifidis, segmentis lanceolatis integerrimis, stipulis bipartitis, segmentis insequaliter bifidis laciniis subulato-setaceis, calyce terminali oblongo trigono, ore trilaciniato laciniis dentatis. Nobis in Lond. Journ. Bot. vol. iii. p. 471. (Tab. CLIX. Fig. II.)

Hab. Falkland Islands ; on tufts of mosses.

Ceespites parvi, inter Muscos intricati, pallide olivacei. Caules vix % unc. longi, prostrati, demiun ascendentes, apicibus supinis radicantibus. Folia imbricata, madore erecta et secunda. Stipules amphe, segmentis setaceis incurvis. Cedyx majusculus, trigonus, latere mferiore latiore, ore ciliato-dentato.

This in some respects approaches the British /. bidentata, but is even more like /. lieteropliylla, from which it may eventually prove not distinct ; its claims rest on the closely imbricated and secund leaves, and more entire segments of the stipules.

Plate CLIX. Fig. II. — 1, plant of the natural size; 2, apex of stem, perichsetium, and calyx; 3, leaf; 4, stipule : — Magnified.

55. Jungermannia subviridis, Hook. fil. et Tayl.; parvula, caule csespitoso prostrato ramoso, foliis laxe imbricatis secundis erecto-patentibus erectisve oblique obovatis quadratisve emarginato-bifidis segmentis obtusiusculis, margine anteriore gibboso, inferiore decurrente, stipulis ovatis bifidis utrinque uni-dentatis. Nobis in Lond. Journ. Bot. vol. iii. p. 473. (Tab. CLIX. Fig. IV.) Hab. Hermit e Island, Cape Horn ; on the ground.
