acute lobes, tips conniving. A few spreading bifid and trifid 

 cellular scales at its base, with many single narrow linear 

 hyaline spreading fimbriae below them. 



Hah. On the ground among other HcpaticcB aiid mosses 

 shaded wet woods south of Dannevirke, County of Waipawa ; 

 1888 : W. C. 



Obs. A species having close affinity with Z. argcntea, 

 Hook, f., and also with Z. flagelliforme, Col. (" Trans. 

 N.Z. Inst.," vol. xviii., p. 250), but differing from the 

 former in habit, in texture, and in colour, in its larger 

 number of lateral cells, and in its not possessing any " cilii- 

 form appendages," or "bristles," or " saw-like teeth" to its 

 marginal bosses ; and from the latter in its branches being 

 6 cells in width, in their not being flagelliferous at tips, in its 

 perianth being basal and much less laciniate, &c. This little 

 plant affords a very pleasing and highly instructive, though 

 tedious, microscopical study. 



2. Z. muscosa, sp. nov. 



Plant prostrate, creeping, forming large thick patches several 

 inches square ; light-green. Stems lin.-l-|in. long, -^in. wide, 

 dichotomous ; branches spreading largely ; nerve stout, dark, 

 flexuous ; margins sinuous, regular ; cells very large, sub- 

 quadrilateral, usually about six in the width of a branch. 

 Long flagellae, or very narrow sub-rigid branchlets, proceed 

 from main stem and axils at right angles. 



Hah. On rotten logs, wet woods near Dannevirke, County 

 of Waipawa ; 1888 : W. C. 



Obs. A species near Z. flagelliforme, Col. (supra), but dif- 

 fering in habit, in its larger size, broader stems and branches 

 with more regular margins, their cells bigger and of a different 

 shape, and the tips of the branches not flagellate. 



Genus 30. Syinphyog3ma, iNIont. and Nees. 



1. S. platystipa, sp. nov. 



Plant small, stipitate, gregarious, roots shortly creeping, 

 2-3 fronds together on a rhizome; erect, lin.-l|-in. high. Stipe 

 slender, pale, sub-rigid, flexuous, flat at top not winged, some- 

 times once branched near base. Frond broadly reniform, 

 -|in.-|-in. broad, 2-branclied; branches short, twice forked; 

 lobes linear, wide, very thin, transparent, bright-green, 

 slightly undulate, margins entire, tips deeply emarginate, 

 nerve scarcely reaching to notch. Cells large orbicular-oblong. 

 Calyptra at base of main forks, three on a plant, sub-peduncled 

 on a small bulbous process, large, broadly reniform, wavy, 

 the ends free not encircling nor adhering ; margin entire and 

 slightly sub-sinuate. Within calyptra 12-14 small erect linear 

 pellucid sacs (antheridia), transversely marked in small
