trifid. Perianth at the base of the stem on a short branch, narrowly 

 and elongated ovate, 6-fold, 120 double row of cells at middle, mouth 

 contracted and contorted, with 30 two-celled setae. Bracts obovate 

 or oblong-quadrate, apex broad, ciliolate; bracteole oval, apex ciliolate. 

 Androeeia not seen. 



Dimensions. — Stems 1 inch long; with leaves 1 mm. wide, diam. 

 .3 mm., leaves with segments, explanate .8 mm. long X 1-1 mna. broad; 

 disc .3 mm. broad at base. .75 mm. at apex, segments .3 to A mm. long, 

 .1 mm. wade at base; cells .05 mm. ; underleaves .6 mm. X -6 mm. with 

 segments explanate, disc .2 mm. Avide at base, .4 mm. upper margin, 

 segments .3 mm. long, ,075 mm. to .1 mm. wide at base ; bracts 1 mm. 

 long X .75 mm. broad; bracteole .75 mm, X -5 mm.; perianth 2.25 

 mm. long X -9 mm. at widest part, apex .1 mm., setae .1 mm. long; 

 archegonia .175 mm. X -05 mm. 



Habitat. — Mamaku Bush, North Island, New Zealand; coll, W. A. 

 Setchell, 1904. 



Observations. — This is a very beautiful and distinct species. I 

 have compared the specimens with the originals from Cape Horn, 

 in the ^Manchester Museum, vrith which they agree, save that they 

 are larger.

Dioicous. Largish size ; light brownish green in color ; densely 

 erectocaespitose. Stems roundish, slightly frontally compressed, 35 

 cortical cells, slightly larger than inner, which are 20 broad and 15 

 high; ramose, pinnate or slightly bipinnate, pinnae short, distant, 

 somewhat regular in length, attenuate, flagelliferous, often secund; 

 slightly ascending, patent-divergent (70°), horizontal (90°) or 

 slightly decurved. Leaves distant, approximate or imbricate near 

 apex; lower (postical) margin slightly decurrent, insertion a little 

 beyond the margin of stem, upper (antical) margin extending to 

 middle of stem, slightly ampliate or truncate ; concave, incurved, 

 clasping the stem except on young branches ; oblong-quadrate, quad- 

 rifid to about one-fourth, basal tooth smallest, segments narrowly tri- 

 angular or lanceolate-acute, 4 to 7 cells wide at their base. Under- 

 leaves as wide as stem from which they stand off, quadrate, quadrifid 

 to about one-third, segments subequal, narrowly triangular to lanceo- 

 late, acute or obtusate. Androeeia terminal on short, narrow 

 branches; bracts closely imbricate, trifid; bracteole oval, acute, bifid 

 to the middle. 



Dimensions. — Stems IV^ to 2 inches long ; with branches 1 mm. 

 wide ; diam. .2 to .3 mm. ; leaves .9 mm. X .7 mm., segments .2 mm. ; 

 cells .03 mm., underleaves .5 mm. X .5 mm., segments .2 mm., peri- 

 gonial bract .5 mm. X .4 mm., perigonial bracteole .4 mm. X -2 mm.
