10. F. ichtkyostoma, sp. nov. 



Plant l|^in.-2in. long; branches tripinnate, much im- 

 plexecl. Leaves tranversely set, sub-vertical, orbicular, 

 margins uneven, tips recurved ; brown-black, but when young 

 green. Perichsetial large, broadly ovate, acute, sub-amplexi- 

 caul. Cells various shapes and sizes, oblong, sub-rhomboidal, 

 their edges uneven and curiously sub-crenulate. Stipule 

 small, reniform, ^Yith a bunch of rootlets at its base ; sinus 

 slightly lateral (resembling a fish's mouth in profile), shallow, 

 spreading, the upper or apical angle larger. Perianth oblong, 

 smooth, sub-i-gonous, largely and bluntly carinate on one 

 side, slightly so and only half-way down on the other ; tip 

 mucronate. 



Hah. On trees, woods, Dannevirke, County of Waipawa, 

 forming large spreading patches ; 1888 : W. G. 



Ohs. A species peculiarly marked in the microscopical and 

 regular crenulate divisions of its cells — a curious (if not unique) 

 character ; also in the oblique sinus of its stipule — whence its 

 trivial name. 



11. F. 2}ulvinata, sp. nov. 



Stems lin.-2in. long, much branched and implexed. Leaves 

 orbicular-cordate, margin slightly uneven. Cells oblong with 

 minute interstitial cellules, also (without epidermis) distinct, 

 beaded. PericliEetial erect, broadly ovate, acuminate, bifid ; 

 lobes acute spreading, sinus deep. Stipule broadly orbicular ; 

 margin slightly irregular ; sinus rather small ; cells guttulate. 

 Perianth fiattish, oblong, smooth, slightly keeled on one side, 

 mucronate ; mucro stout, obtuse. 



Hab. On living trees, woods, Dannevirke, County of Wai- 

 pawa, forming big patches ; 1888 : W. G. 



Genus 27. Zoopsis, Hook. f. and Tayl. 



1. Z. hasilaris, sp. nov. 



Plant terrestrial, minute, sub-erect, and decumbent, gla- 

 brous, pale-green, densely gregarious. Eoot long (for plant), 

 straight, capillary, hyaline, white with minute spreading 

 lateral rootlets ; stem very short, branches simple, and once 

 branched, spreading, 3-4: lines long, sV^- wide, wholly com- 

 posed of an innumerable number of large transparent orbicu- 

 lar cells, their single narrow walls or divisions (in appearance) 

 intercircling each other, central nerve dark and very stout ; 

 the branches linear, 6 cells wide, pretty regularly sub-lobed 

 ■with alternate gibbous lateral projections, each composed of 

 2-3 cells with a smaller hemispherical cap, or boss, on the 

 outside one, their tips broader, obtuse. Perianth single, basal, 

 sub-sessile, erect, obovate, -^jjin. long, composed wholly of cells, 

 no nerves ; mouth cut into five rather long acuminate and
