5. G. trichotoma, sp. nov. 



Plant procumbent, spreading, 2-3 inches long, much 

 branched, main branches generally trichotomous at tips ; stems 

 leafy, stout, with many brown rootlets at bases, branches about 

 1 inch long, 4 lines wide, linear, obtuse, slightly rooting at 

 bases ; rootlets brown. Leaves a pleasing green, spreading, 

 rather distant below, base of stem bare, close above, oblong- 

 ovate, obtuse, sharply and closely serrate, laciniate-ciliate on 

 basal margins, a ridge or plait running from lower anterior 

 angle of dorsal lobe to the margin of the ventral, with a few 

 other small, scattered, short creases or low plaits on its lamina ; 

 dorsal similar in shape and smaller, apices free, bases broadly 

 rounded. Stipule large, quadrifid, segments much laciniate- 

 ciliate : ciliae long, flexuous, pellucid, jointed (as in G. chloro- 

 phylla). On the stem, between dorsal and ventral lobes, are two 

 transverse lateral rows of finely laciniated processes or leaflets. 



Hub. Among other Hepatic® and mosses on prostrate trees, 

 wet forests near Norsewood, County of Waipawa ; 1885 : W.C. 



Obs. A fine species, having close affinity with the preceding, 

 G. heterocolpos, in its additional stem-leaflets (which, however, 

 are longer, narrower, more numerous, and differently situated), 

 but widely differing in its compound ciliated stipules, etc. 



6. G. chlorophyUa, sp. nov. 



Plant very small, under J inch long, obovate-oblong, broadest 

 at tip, very obtuse, simple, and 2-4 branched from near base. 

 Leaves closely imbricated, pale green, whitish tipped, oblong, 

 obtuse, margins irregular and sub-laciniate, much ciliated, each 

 lacinia ending in a long cilia ; ciliae all jointed ; dorsal lobe 

 similar, but much smaller; cells orbicular. Stipules broadly 

 cuneate. or sub-quadrate-flabelliform, laciniate-lobed, each lobe 

 ending in two large cilire : sinus broad. 



Hab. On rotten logs, watercourse ; deep forest near Norse- 

 wood, County of Waipawa ; 1883-85 : W.C. 



Obs. A species near to G. ciliata, Mitt., but differing in its 

 laciniated stipules and leaves, smaller dorsal lobes, and much 

 smaller size. It has a very hoary appearance on both sides, 

 from its pale colour and long cilias. It is apparently scarce, 

 having only very sparingly been met with. 



7. G. bieolor, sp. nov. 



Plant densely gregarious in large patches, simple, broadly 

 obovate, 4-6 lines long, 2 lines broad at tips. Leaves light- 

 green below, bright yellow-green above, sub-imbricate, spread- 

 ing, sub-falcate, finely laciniate-serrate, especially at tips; dorsal 

 lobes upper margins entire, rounded and broad at base, and 

 overlapping on stem ; tips truncate and minutely serrulate ; 

 cells sub-quadrate and oblong. Stipules sub-quadrate, bi-lobed
