152 J. notophylla it swells much in moistening, and assumes a stout and as it were greasy appearance, from the peculiar texture of the distended cells. The broad stipules, reaching nearly across the back of the stem, resemble those of /. Billardieri, and are as regular and close along the whole plant as the scales of a snake. Plate LXIV. Fig. V. — 1, a specimen of the natural size ; 2, front; 3, back, and 4, side view of stem ; 5, a leaf; 6, calyx and perichaetium : magnified.

(Tab. LXIY. Fig. IV.)

Hab. Lord Auckland's group ; creeping over the caudices of Ferns, rare.

Canles subsolitarii, vage repentes, v. casspites laxos pianos sub 1 unc. diametro formantes, planiusculi, procumbentes, parce divaricatim ramosi, 1 unc. longi, latiusculi, albidi. Folia tenerrima, membranacea, laxe eellulosa, pellucida, dense imbricata, pulcherrirae ciliato-dentata, valde concava, profunde biloba, lobis valde inaequalibus, lobo anteriore imdto minore supra faciem anticam caulis extenso, stipulam referente ; folium superius in sinu concavo inferioris receptum. .^

In some respects this remarkably beautiful species resembles a Gottscliea, but it is in reality more allied to the genus Scapania of Liudenberg, from whose pubbshed characters it differs only in the presence of stipules ! From what we have seeu of the fructification, however, it widely departs from that group. The calyptra, in a specimen from M'Quarrie's River (New Holland), is globose, destitute of any calyx, surmounted by a truncated stvle, rough with numerous barren pistilla on its surface, and sin-rounded by scales ; the scales are laciniate, the outermost the narrowest, and all enclosed in a triphyllous perichaetium.

Hab. Lord Auckland's group ; amongst mosses and other Hepatiea. This little species is probably not uncommon in the high southern latitudes, having been also gathered in Kerguelen's Land.

26. Jo'germaxn'ia tenacifolia, Hook. fil. et Tayl.j caule rigido tenui laxe csespitoso erecto subsimplici flexuoso, foliis distantibus patentibus rigidis tenacibus elliptico-oblongis obtusis integerrimis basi angustatis marginibus planis v. recurvis, stipulis conformibus minoribus integris bifidisve. (Tab. LXIV. Fig. VI.)

Hab. Lord Auckland's group; amongst other Hepatica, mosses, &c., in exposed situations near the tops of the hills.

Ceespites laxi, fusco-brunnei v. atri. Canles graciles, vix 1 unc. longi, rigidi, vix ramosi, flexuosi. Folia stipulis conformia semper patentia, dura, rigida, opaca, rarius reeurva, fusco-brunnea.

We know of no species with which the present can at all be compared. The leaves and stipules are so nearly alike and so regidarly stiff and patent, that the stems look pectinated with a triple row of spines, standing at regular intervals. This rigidity, combined with the slender habit, is very remarkable.
