recurved. Leaves alternate, close, sub-imbricate, obliquely 

 cordate-orbicular, 2 lines long, very obtuse, narrowly margined, 

 semi-amplexicaul, spreading, decurved, dusky pale-green rather 

 obscure (when dry, margins revolute) ; ventral margin and apex 

 denticulate, teeth irregular and distant, acute and obtuse, base 

 free, produced, overlapping stem ; dorsal margin entire, nearly 

 straight, slightly decurrent, thickened and contracted at junction 

 with stem, small and sub-orbicular at base. Cells very small, 

 oval, with double walls and minute cellules in them, crowded, 

 distinct. Male : Spike near top of branch, broadly conical, 

 5-jugate; scales rather large, entire, recurved ; sometimes 3-4 

 spikes on one branch, each separated by a few leaves. Fruit 

 not seen. 



Hab. Forming small thick cushion-like tufts on branches of

 Norsewood, County of Waipawa ; October 1886 : W.C. 



3. P. heterophylla, sp. nov. 



Plant small ; rhizome wiry, creeping ; stems erect, sub-rigid, 

 1^ inches high, 2 lines broad, distant, simple and forked, leafy 

 to base, reddish-brown ; branches few, long and straight, with 

 a few short branchlets at top, pale reddish-green and semi- 

 transparent. Leaves bright-green sub-amplexicaul, slightly 

 decurrent both sides on stem, the ventral bases scarcely over- 

 lapping ; those on main stems triangular or deltoid-oblong, their 

 apices very obtuse, 12-14 irregular long laciniate teeth on 

 ventral margin and at apex, of which about 6 are apical ; leaves 

 on the branches xfrth inch wide including stem, with fewer teeth ; 

 and those on the ultimate branchlets are exceedingly small, being 

 only with the stem ^th inch wide, oblong, the ventral margin 

 rounded, the dorsal straight, and both entire ; the apex truncate 

 with 2-3 very long and distant spiny teeth. Involucral narrow, 

 erect, with 3-4 long spreading lacmia? at apex. Cells minute, 

 sub-orbicular, crowded, walls thick with numerous minute inter- 

 mediate cellules. Perianth small, terminal and solitary at end 

 of stems and main branches, peduncled, narrow-campanulate, 

 xnth inch long, whitish ; base tapering, constricted ; mouth 

 broad cilio-laciniate ; teeth many, erect. Capsule sub-obovoid, 

 brown ; valves oblong-lanceolate, obtuse, dark- veined longi- 

 tudinally ; seta exserted, 2 lines long. 



Hab. On logs and trunks of trees, wet woods near Danne- 

 verke, County of Waipawa ; 1887 : W.C. 



Obs. This is a small delicate-looking slender wiry species, 

 allied to P. distans, Col.,* and P. distinctifolia, Lind. Its small 

 leaves resemble those of P. spinulosa, Nees and Mont., a British 

 species.
