154 flaccidis ascendentibus, foliis contiguis patentibus disticliis oblongis biiidis segmentis divaricatis acuminatis integerrimis, stipulis minutis lanceolatis bipartitis integerrimis, calyce obovato compresso trigono, ore bilabiate) dentate

Hab. Lord Auckland's group ; in large tufts upon the moist trunks of trees.

Ccespites lati, interdum 2-3 unciales, supra albidi v. pallide straminei, inferne dilute bnmnei. Caules 1-2 unciales, valde intertexti, elougati, graciles, simplices v. rarius ramosi, apices versus paulo curvati, flaccidi, cellidosi. Folia e caide prostrato suberecta, paulo divergentia, hinc quasi biserialia, oblonga, versus medium sublatiora, emarginata v. bifida, siuu obtuso, segmentis acuminatis ; perichcetialki conformia, erecta. Stipules bifidse, integerrimae, rarius basi extus unidentatae. Calyx membranaceus, pellucidus, trigonus, latere anteriore latiore, angulis incrassatis opacis, ore niajusculo bdobo, lobis acuminatis argute dentatis. Capsula ovalis, pedunculo unc. longo.

This species is very nearly allied to and apparently intermediate between the /. bidentata, L. and J.perpusilla, nobis, the former in particular, from which it is only to be distinguished by the smaller size and the entire segments of the stipules ; from the latter it may be known by being at least double the size, by the more tufted habit, the deeper emargination of the leaf, their more acuminate segments and larger cells, and by the deeper division of the stipides. There are numerous radicles issuing from the stem throughout its whole length, their position is immediately above the stipules, whence it seems highly probable that, when less tufted, the plant may be wholly creeping. This species will be figured in the Flora of New Zealand, of which island also it is a native.

32. Jungermannia perpus'dla, Hook. fil. et Tayl. ; caespitosa, caulibus ascendentibus subrarnosis, foliis erecto-patentibus subsecundis oblongo-ovatis biiidis segmentis divaricatis subobtusis integerrimis, stipulis minutis oblongis biiidis v. rarius laceris, perigoniis ovatis. (Tab. LXIV. Fig. IX.)

Hab. Campbell's Island ; mixed with other Hepatka and mosses, sparingly.

Ccespites parvi, pallide flavi, laxi. Caules vix 3 lin. longi, subramosi, gracUes. Folia patentia, ovata, basi lata, bifida v. rarius trifida, siuu obtuso. Stipules diametro caulem aequantes, in segmentis 2 aequilongis integris v. rarius sectis divisae. Perigonia e foliis ventricosis imbricatis ad apices recurvis in spicam brevem ovatam dispositis. Perichcetii abortivi folia elongata, subdentata, sinu minus profunda.

Under the preceding, to wluch this bears most affinity, we have pointed out their relative peculiarities.

33. Jungermannia grisea, Hook. fil. et Tayl. ; caespitosa, procumbens, caulibus implexis raniosis, foliis patentibus approximates supremis congestis oblongo-rotundatis integerrimis marginibus recurvis, stipulis bipartitis segmentis hinc unidentatis v. rarius multipartitis, calyce terminali oblongo trigono compresso ore dentato. (Tab. LXIV. Fig. VIII.)

Hab. Lord Auckland's group ; creeping amongst mosses, &c., rare. Ccespites depressi, plani, fusco-olivacei. Caules 1 unc. longi, vage ramosi, flexuosi, apicibus ascendentibus.

Folia inferiora disticha, marginibus recurvis, convexa, suprema appressa, secunda, in capitulum congesta, substantia crassiuscula, luride flava, subpellucida, cellulis minimis. Calyx 1 bn. longus, trigonus, angulis incrassatis opacis, latere inferiore latiore, ore triangulari dentato. Perichcetii folia tria, erecta, horum duo superiora majora magisque elongata quam in fobis caubnis, rotundata, integra ; tertium v. stipulare, oblongum, emarginatum, marginibus recurvis.

This very closely resembles the L. discedens, Nees ; it is, however, a larger species, of a paler colour. The leaves are erecto-patent and not recurved, their tops entfre, the stipules are divided, and each segment is again divided or bears a tooth at the outer margin.
