shorter and closer branclilets that are rarely capillary, and when 

 so, finer than fine hah and coloured ; in its larger leaves with 

 larger open cells visible to the naked eye, and in their much 

 longer segments which are also in single-celled rows throughout. 

 A truly elegant plant. 



3. L. subverticillata, sp. nov. 



Plant small filiform procumbent spreading, closely adhering 

 to rotten wood, much and irregularly branched ; light-green. 

 Main branches 2 inches long and more, sub-bi-pinnate, narrow, 

 linear-oblong ; branclilets short, alternate, tips occasionally but 

 seldom capillary. Leaves highly cellular, close set, overlapping 

 (having a sub-verticillate appearance), sub-oblong-quadrate, 

 3- (sometimes 4-) fid; lamina very short, scarcely any; segments 

 very long, articulate, incurved. Stipules similar, but smaller 

 and more distant. Perianth terminal on short lateral branclilets 

 (sometimes two close together), very large for the plant, 

 cylindrical, 2 lines long, vertical, largely ciliate at tips with 

 6-9 long flexuous cilias ; cells large, narrow-oblong ; involucral 

 leaves large, cellular, sub-broadly-ovate, tips slightly laciniate. 



Hab. On rotten logs, forming small thick patches ; in wet 

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



Obs. A very neat little species of a pleasing green colour ; 

 its affinities are with L. capillaris, Lind. 



4. L. minuta, sp. nov. 



Plant minute, prostrate and creeping, wiry, irregularly 

 branched, pale-green, with long white capillary pellucid radicles 

 below. Main branches about 1 inch long, with many capillary 

 branclilets ^ - f inch long. Leaves rather small, close set, and 

 sub-imbricate, patent, quadrate, 4-dentate, larger and more 

 distant on the main branches ; lamina large ; teeth short, 

 broadly-triangular, acute, incurved ; cells small, sub-orbicular, 

 distinct, much larger in the centre of leaf. Stipules minute, 

 distant, similar to leaves but much smaller, 3-4-toothed. 

 Perianth lateral, sub-sessile on main stems ; involucral leaves 

 rather large, oblong-ovate, slightly laciniate ; cells large. 



Hab. Among mosses and small Hepatica, on decaying logs ; 

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



Obs. A species having close affinity with L. lavifolia, Lind. 



Genus 14. Mastigobryum, Nees. 

 1. M. concinnatum, sp. nov. 



Plant a pleasing light-green, densely and regularly tufted, 

 shortly creeping, imbricate ; stems f - 1-| inches long, dicho- 

 tomous ; branches -J inch long, linear, 1£ lines wide, obtuse, 

 divergent, sending down long scaly and hairy rootlets ; young 

 branches and rootlets highly cellular. ' Leaves close, distichous.
