haii-y and scaly beneath at bases. Leaves alternate, distant on 

 stem below, close, and slightly imbricate at their bases above, 

 oblong, spreading, plaited about the tips, which are very thin, 

 laciniate-lobed ; lobes largely and sharply serrate ; tip of the 

 ventral lobe sub-acute, of the dorsal broad and obliquely trun- 

 cate, and both finely serrate ; axils clear ; cells large, oblong, of 

 various sizes, minutely and regularly papillose, but clear and 

 orbicular at tips. Stipule large, free, li hues wide, sub-cuneate- 

 quadrate, narrowest at base, much cilio-laciniate on three sides ; 

 laciniae long, flexuous, very acute, bifid ; sinus long, margins 

 subsinuate and laciniate. 



Hah. Among mosses, on rotten logs in wet shaded woods, 

 near Norsewood, County of Waipawa ; 1886 : W.C. 



Ohs. A species having pretty close affinity with G. macroam- 

 phigastra, Col.* 



2. O. compacta, sp. nov. 



Plant small, compactly gregarious, nestling together in little 

 tufts or cushions, procumbent and sub- erect, with a profusion of 

 dark-red rootlets below. Stem stout, leafy to base, simple, but 

 often with 2-3 minute branchlets at top, i- f inch high, 3-8 

 lines wide at tip including branchlets ; lower leaves green, but 

 very pale-green at tops bearing the appearance of whitish round 

 buds. Leaves amplexicaul, closely imbricate ; ventral lobe very 

 thin, ovate-acuminate, acute, much plaited with fine short plaits 

 or ridges running diagonally to margins, the upper margin 

 finely serrate, the lower margin largely laciniate ; cells large, 

 oblong, clear, with minute orbicular interstitial ones ; dorsal 

 lobe broad, much arched, apex obliquely truncate and finely and 

 sharply serrate, anterior margin slightly serrulate, the basal 

 portion entire and overlapping ; cells much as in the ventral 

 lobe, but more crowded and not so clear. Stipules large (for 

 the plant), bilobed half-way through, laciniate on all margins; 

 laciniae large, very cellular ; cells large, oblong and clear below, 

 orbicular and double-walled above. 



Hab. On rotten logs, forming little dense closely-com- 

 pacted patches, in low wet woods, near Norsewood, County of 

 Waipawa; 1886: W.C. 



Ohs. A peculiar-looking little species, well marked, by its 

 habit of growth and its handsome largely-laciniate stipules.
