serrate above, laciniate below ; dorsal shorter, tips sub-truncate 

 and serrulate, rotund and overlapping at base, and much broader 

 than the ventral lobe, margin there entire, or under a high power 

 minutely serrulate in the anterior portion, the apical serrulate 

 on both margins with a narrow plait extending from lower 

 point of apical margin to outer margin of ventral lobe ; invo- 

 lucral narrow, 2 lines long, much and compound laciniate, con- 

 nate at base ; cells orbicular. Stipule very large, sub-quadrate, 

 H lines wide, snb-bilobed at tip, much laciniate ; lacinise largely 

 cellular throughout. 



Hab. On rotten logs, among other Hepaticce and mosses, 

 Seventy-mile Bush, County of Waipawa ; 1883: W.C. 



Obs. A very distinct species, from its large and broad 

 stipules, and the concave lobes of its leaves ; hitherto, however, 

 it is rather scarce. 



4. G. heterocolpos, sp. nov. 



Plant small, procumbent, spreading, pale green, stems 

 stoutish, leaved to base, 1-H inches long, 3-4 lines broad, 

 much (5-6) branched, branches short, fiattish ; rootlets purple, 

 very numerous, short and matted below. Leaves sub-ovate, 

 falcate, acute, finely and sharply serrate ; ventral suberulent or 

 minutely and closely roughish at tips on both sides, laciniate- 

 ciliate on lower basal margins ; dorsal similar in shape, but 

 much smaller and smooth, obtuse and sub-truncate at tips, with 

 finer and more distant serratures, and a ridge or plait running 

 from the lower angle of apex to outer margin of the ventral 

 lobe, basal margin almost entire ; cells sub-orbicular, cell-walls 

 thick. Stipule rather large, sub-quadrate-cuneate, narrowest at 

 base, bifid, lobes divergent, each lobe sparingly and coarsely 

 laciniate above, not below, sinus large orbicular. On the 

 stem on each side, within the two lobes, and in their axils, are 

 several small narrow scale-like laciniated processes or leaflets, 

 and also in minute tufts near to the bases of the stipules, but 

 separate and above them. 



Hab. In forest, Seventy-mile Bush, County of Waipawa ; 

 1882: W.C. 



Obs. The exact locality of this peculiar species is at present 

 unknown ; the few specimens I have were brought hurriedly 

 away, and merely for comparison, believing them to be identical 

 with other species lately detected there by me. I may, however, 

 find it again.* It is a highly curious species, in its possessing 

 those minute, scale-like leaflets in the axil! as of its leaf-lobes ; 

 in this character, however, it is something like G. nobilis, Nees, 

 the only other species known to possess it. [But see the fol- 

 lowing species, recently discovered.] 



* Since writing the above, I have again found this plant ; June, 1885 ; 

 its exact locality is in wet low woods, near Norsewood.
