15S FLOEA ANTAECTICA. {AmUand and
This and the following may be considered representatives of the British J. reptans, L., to wldch the present is
very nearly allied, though differing in the much smaller size, the less pinnated stems, the more distant leaves which
have not the singularly prominent cells of the northern plant, and especially in the short perichætium and elongated
caho;. It is also a native of New Zealand, in the Flora of which countiy it ivill be figm-ed.
45. Hook. fil. et Tayl.; subcæspitosa, caule valido repente pinnatim ramoso,
ramis breribus, foliis plus minusve imbricatis patentibus v. incurris cellulosis latissime obovato-quah-

transverse elongatis tri-quadridentatis. (Tab. LXV. Fig. V.)
H a b . Lord Auckland’s group ; creeping among tufts of other Hepaticæ, on trunks of trees, &c.
Canles inter Hepáticas alias Muscosque dispersi, pallide flavo-ohvacei, breviusculi, rix F uuc. longi, validi, crassiusculi,
cellulosi ; ramis plerumque inconspicuis, brevibus, altérais, versus apices attenuatis. Folia caulina pleriunque

segmentis incm-vis v. planis, obovatis, 3-5-fidis, sæpius 4-fidis, celluhs majuscuhs. Stipulæ caule vix latiores, segmentis
brevibus.
This plant approaches nearer to the J. reptans, L., than the former ; it is, however, very much smaller, the
leaves more closely imbricated, generally more deeply divided and narrower at the base.

46. J ungermannia tenax, Greville, in Annals o f Lyceum o f New York, vol. i. p. 277. pi. 23.
H ab . Lord Auckland’s group ; on the dry trunks of trees and on the ground.
A curious little species, first described by Dr. Greville, who gives an excellent figui*e of it, from New Holland
specimens.
47. J ungermannia tetradactyla, Hook. fil. et Tayl. ; cæspitosa, implexa, caule debili prostrate sub-
pinnatim ramoso, foliis subremotis distichis patentibus basi quadratis quadrispinosis spirds articulatis, stipulis
minimis quadripartitis, calyce elongato cylindraceo ore contracto cdiato.
H a b . Lord Auckland’s gro u p ; creeping over patches of J. coalita.
Cæspites 1-2 imc. lati, paUide flavo-virides. Caules interdum 1 unc. longi, innovationibus plmimis ramosi ;
ceUulæ externæ latæ, peUucidæ, albæ, centrales virides, opacæ, hinc cauhs sub lente quasi ala membranacea cinctus
appareat. Folia cauhna remota, ramuliua (pleramque superiora) conferta, basi angusta, deiude latiora, in spinas
elongatas desinentia. Stipulæ caule vix latiores, segmentis subulatis.
Closely aUied to the J. centipes, nobis, of Tasmania, from which it may be distinguished by the (transparent)
more branched and pinnate stems, the more distant and patent transparent leaves, which ai-e more deeply divided,
with the segments elongated and setaceous : the two species are very near in other respects.
From New Zealand we have this plant with calyces and perigonia; the former are remarkably large in proportion
to the size of the plant, being as long as the shoots which bear them, they are ovato-cylindrical and slightly
bent on one side. The perichætial leaves are erect, with a longer entire portion or base than the cauline. Pcrigonia
forming cylindrical spikes, their leaves large, bifid above with tumid bases, each containing in its axiUa a single minute,
round, brown, pediceUated anther.
48. J ungermannia dispar, Mont.; caulibus elongatis cæspitosis ramosis, fohis laxe imbricatis rarius

H a b . Lord Auckland’s group and Campbeh’s Island; on the ground.
49. J u n g e rm a n n ia hippurioides, Hook. fil. et Tayl.; minima, laxe cæspitosa, caule procumbente ramoso,
fohis subimbricatis patentibus obovatis bi-trifidis basi angustis, segmentis hnearibus subacutis, stipuhs
minutis valde inconspicuis erectis appressis trifidis. (T a b . LXV. Fig. VII.)
H a b . Lord Auckland’s group; on decayed bark, and at the roots of grasses and fems in wet places.
Cæspites per innovationibus vagis intertexti, pallide ohvacei. Caules vix unciales, irregulariter pinnati, una cum
fohis densis crassiusculi. Folia conferta, imbricata, patentia, quasi verticillata, profimde bi-trifida rarius quadiifida,
laciniis cellulosis inarticulatis. Stipulæ valde inconspicuæ, cauh latiori arcte appressæ, pleramque in segmenta
tria divisæ.
A very distinct httle species, though not easily characterized ; the figure ivill give the best idea of its habit and
peculiarities. I t is most nearly alhed to the J. tetradactyla, nobis, (vid. ante) from which it may be recognized
by its shorter and more patent leaves, which, as weh as the stipules, are usually trifid.

basin versus dentata, cætermn in lacinias cmwatas bifidas partita. Stipulæ F magnitudine folii, imbricatæ, con-

This is a very beautiful plant, much larger aud of a different aspect from any of the fonner.

H a b . Lord Anckland’s group ; common in the U'oods, forming large tufts.
A very handsome species, variable in size ; of a much larger and more erect habit, and ivith broader leaves
than the J. Novæ HoUandiæ, the latter have larger cells also.
