with numerous dark-purple rootlets. Leaves close, imbricate, 

 very thin ; ventral lobe oblong-ovate, tips rounded with 2-4 

 narrow plaits running obliquely from dorsal lobe to margin ; 

 margins minutely serrulate and irregularly sinuous and notched 

 from the plaits ; the upper basal margin largely ciliate ; cilire 

 capillary, long and wavy, composed of several single cells placed 

 longitudinally : the dorsal lobe short, only frds length of the 

 ventral, sub-trapeziform or sub-cordate-dimidiate, minutely ser- 

 rulate, its upper basal margin rounded and produced beyond the 

 ventral lobe but not really wider than it ; apex broad and very 

 truncate. Cells sub-orbicular, close, with double walls contain- 

 ing minute pellucid circular cellules. Stipules large, somewhat 

 sub-quadrate in outline, narrowest at base, 3-4-lobed, much 

 laciniate and largely ciliate ; cilia? long, jointed, very flexuous 

 and acute ; cells narrow-oblong, their ends obtuse and truncate, 

 closely compacted. On the stem between the leaves are several 

 long narrow irregular cellular processes or leaflets, in 2-3 rows, 

 patent and much ciliated. 



Hab. On the ground, in damp woods near Danneverke, 

 County of Waipawa ; 1887: W.C. 



Obs. A species near G. trichotoma, Col.,* but differing in 

 being much smaller and simple, with notched margins to its 

 leaves, and particularly in its very short and broadly truncate 

 dorsal lobe. 



2. (t. flaro-virens, sp. nov. 



Plant very small, gregarious, prostrate, broadly obovate, 

 sub i inch long, simple ; yellowish-green with red rootlets at 

 base. Leaves oblong-ovate, obtuse, margins slightly serrate ; 

 the ventral basal portion shortly laciniate-serrate ; the margin 

 of the dorsal lobe very slightly serrulate, tip oblique, rounded, 

 the base slightly produced, its margin nearly entire. Stipule 

 large, sub-quadrate, bilobed ; lobes broad, coarsely laciniate 

 with numerous broad lacinise; sinus large, extending ; \rd down. 

 Cells small, orbicular and very regular, with minute pellucid 

 cellules in angles between cells ; oblong and larger at base of 

 stipule. 



Hub. On the ground, sides of streams, in woods with the 

 preceding species, G. truncatula : 1887 : W.C. 



Obs. A species having affinity with G. pallescens, Col., and 

 G. IcBte-virens, Col. i 



3. G. squamosa, sp. nov. 



Plant large, sub-ascending, 7 incbes long. Stem stout, dark- 

 brown, leafy, simple, with 2-4 short and forked branchlets at 

 top; base bare. Leaves alternate, large, green, very distaut
