small, compact, sub-orbicular, larger at base, with thick 

 irregular double walls and cellules in them. 



Hah. On ground, sides of Mount Tongariro, Countv of 

 East Taupo ; 1887 : Mr. H. Hill. 



Obs. Only a few" specimens of this very distinct species 

 seen ; picked out from among P. alpina (infra). 



■5. P. subconnata, sp. nov. 



Plant pale-brownish, slender, erect, lin.-2in. high, l-^- lines 

 wide, simple and once-forked (about middle), flexuous, leafy 

 nearly to base, the leaves very small and distant below. 

 Leaves opposite, orbicular, very nearly connate, j'-in. diameter, 

 margins slightly uneven, with a few (2-5) minute denticula- 

 tions at top, sometimes sinuate only, wavy, sub-amplexicaul, 

 patent, recurved, the lowest entire. Cells sub-orbicular, of two 

 sizes, one large distant and clear, and one minute close and 

 numerous surrounding the larger ones. Male spikes on the 

 middle of branches, large (for plant), 2-3 lines long, with 

 9-14 pairs of scales, sometimes two spikes at a short distance 

 from each other ; tips recurved, entire. 



Hab. Among other Hcpatica and mosses foiuiing patches 

 ■on trees, woods near Dannevirke, County of Waipaw a ; 1888 : 

 W. C. 



§ 3. Stems erect from a creeping rhizome, tall, much 



branched, dendroid. 



6. P. longissima, sp. nov. 



Plant large, sub-erect and pendulous, sub-rigid. 4in. high ; 

 stems black, leafy to base, branched above ; branches few, 

 very long (2in.-4in.), 3 lines wide, bipinnate, sometimes sub- 

 fascicled and opposite at middle of main stem, divergent ; 

 branchlets few, sub-opposite, spreading. Leaves brownish- 

 green, sometimes green splashed with brown (giving out a 

 brown colour in soaking), close, imbricate, concave, sub- 

 trapezoid-triangular, 1^ lines long; tips truncate, 3-toothed, 

 with usually two teeth below apex on each margin, the rest 

 entire and straight save 5-7 long flexuous ciliate teeth on 

 basal anterior margin, which largely overlaps on stem, meet- 

 ing and standing out like a ridge, their sinuses broad and 

 rounded ; posterior margin recurved lengthways, decurrent on 

 stem, almost meeting at lowest points. Cells orbicular, with 

 round interstitial cellules. Perianth (old) narrow oblong- 

 ovate, mouth sub-truncate, obtuse, with a few coarse teeth. 

 Cells linear-oblong, close together. 



Hab. On trees, thick woods, Dannevirke, Countv of Wai- 

 pawa ; 1888 : W. C.

Ehizome long, slender, branched, creeping. Plant sub-
