plexed ; branches alternate, distant, straight ; tips flexuous,. 

 acute. Stem lin. high, pale, succulent, with red hairs in 

 scattered dense bunches. Frond sub-flabellate-ovate, -Jin. 

 long, pinnately branched; branches few (4-9), simple, close 

 not imbricate, pale -green. Leaves — lower on main stem, 

 scale-like, distant, deltoid, entire, apiculate ; nerve 0, instead 

 of a nerve longitudinal cells extending throughout to apex,, 

 and cells of lamina oblong-hexagonal : upper on main stem,, 

 close not imbricate, oblong-ovate, dimidiate, margined, slightly 

 serrate on upper apical portion, more so on the anterior 

 margin, tip much apiculate, biserrate : on branches, narrower 

 acuminate : dorsal leaves on main stem, sub-orbicular, mar- 

 gined, much apiculate ; nerve stout, extending two-thirds of 

 leaf ; cells clear, oblong, rather small, with minute cellules, 

 smallest at margins, large at centre and base : leaves on 

 branches narrower, broadly oval, entire, margin slightly un- 

 even ; tip very apiculate, the mucro long and flexuous. 



Hab. Among stones and pumice, sides of Mount Tonga- 

 riro. County of East Taupo ; 1887 : Mr. II. Oicen. 



Obs. The roots of this little plant are curious, widely 

 differing from those of other species of this genus, no doubt 

 owing to its high, exposed, and arid habitat. I regret not 

 receiving any fruiting specimens. 



2. H. manj ilia turn, sp. nov. 



Stem l^in. long, sub-rigid, dry, flexuous, flattened, with 

 distant small scarious scales, reddish with dark-red rootlets- 

 scattered in little bunches. Frond small, oblate-orbicular, 

 iin. wide, with 16 short spreading branches, pale-green. 

 Leaves close, imbricate, ovate, acute, apiculate, margined, a 

 few minute teeth near tip ; nerve stout, extending nearly to- 

 apex ; cells small, regular, oval, with double walls and minute 

 cellules ; dorsal leaves on main stem deltoid - rotund, inar- 

 gined, entire, very apiculate; nerve broad, strong, percurrent ; 

 cells small, oblong and rhomboidal, with minute cellules, very 

 long at centre and base, smallest at margins ; leaves on 

 branches orbicular, strongly margined, minutely uneven,, 

 serrulate at tip, cuspidate, stout ; nerve excurrent, stout, 

 prominent. 



Hab. With preceding, sides of Mount Tongariro ; 1887 : 

 Mr. H. Hill. 



Obs. A single specimen picked out from among a lot of 

 scrap and damaged mosses. 



3. H. flaccidum, sp. nov. 



Stem slender, fin. high ; branches simple, fin. long, loosely 

 spreading, soft, flaccid. Leaves — on stem, ovate, acute, 

 serrate, cuspidate ; on branches, ovate, acute, serrate : dorsal,.
