emerald-green. Stem slender, usually A- inch, sometimes 1 inch 

 long, simple (rarely forked, or with 3 main-stem-like branches), 

 scaly from base ; scales sub-foliaceous, distant, scattered, sub- 

 ovate-acuminate, patent. Frond orbicular, lj-l^- inches dia- 

 meter ; branches few, alternate, open, radiating, very narrow. 

 Leaves (lateral) sub-distichous, distinct, free, alternate, dimi- 

 diate, orbicular-ovate, serrate, tip very acuminate, the bases large 

 and overlapping; nerve extending fths of leaf; cells minute, 

 sub-orbicular, guttulate, crowded : (dorsal) deltoid-orbicular, 

 ciliate, nerveless, tip acuminate very long ; cells larger and 

 clearer ; a single long flexuose spreading seta alternate from 

 each dorsal leaf: (perichaetial) outer leaves sub-orbicular, con- 

 cave ; the inner ovate-acuminate, margins entire ; tips very 

 long, piliferous, flexuous ; cells long linear, very close. Fruit- 

 stalk 3£ lines long, twisted, thickened at top, red-brown, vagi- 

 nant, 2-12 together on a stem. Capsule cylindrical, oblong, 

 constricted below mouth, tubercled at base, horizontal and 

 inclined, red-brown ; cells of capsule broadly oval with double 

 walls and minute cellules in them. Teeth, outer, brown, subu- 

 late, very acuminate, tips sub-piliferous, with closely barred 

 double lateral lines and a short faint median line, margins dark ; 

 inner teeth, short, pale, blunt, loosely barred. Calyptra (imma-

 base white, pale-green above. Operculum not seen. 



Hab. On the ground, shady ravines, forest south of Danne- 

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



Ohs. A species having pretty close affinity with H. tamaris- 

 einum and H. rotulutum, Hedw. Its habit of growth more open 

 and scattered than obtains in the other New Zealand species of 

 this genus. A truly elegant moss.

 cate, sub -vertical, spreading, narrowly margined with a dark 

 line, edges unequal entire and slightly undulate, mostly more so 

 on one side, decurrent on upper surface ; cells minute, orbicular,
