14. M. nitens, sp. uov. 



Plaut procumbent, creeping, pale yellowish-green, glossy. 

 Stems 2 inches long, flexuous, wiry and bare below, stout above 

 and very leafy, 1^ lines wide (including leaves), dichotomous, 

 tips recurved. Leaves opposite, close, slightly imbricated, very 

 regular, falcate, sub-oblong-quadrate, dimidiate, the basal por- 

 tion more than twice as broad as the apical but not overlapping 

 stem, truncate, trifid; teeth long, acute ; sinus broad with some- 

 times a minute tootlalet ; narrowly margined, margins uneven, 

 minutely and sparsely toothed on both sides near apex, dorsal 

 margin much arched, ventral excised. Cells minute, oblong- 

 orbicular, distinct, nearly alike throughout, but large at basal 

 centre. Stipules free, but as close as possible to bases of leaves 

 as if connatOj rather large, wider than stem, quadrate, patent, 

 recurved, the margin coloured dark purple, laciniate-serrate 

 above with 4-6 acute irregular teeth, those at the two angles 

 largest ; sides sinuous with generally 1 large tooth above the 

 middle. Cells : central and basal very minute, oblong, distinct, 

 ranged regularly in longitudinal rows; the marginal larger, 

 clearer and united. Flagellas very numerous ; upper short, 

 stout and scaly ; lower, very long and filiform with hairy ends. 



Hab. Woods near Norsewood, County of Waipawa ; form- 

 ing large thick patches on bark, and on dry vegetable debris ; 

 1886: W.C. 



Ohs. A species near M. olivaceum, also M. compactum (supra). 



15. M. parasiticum, sp. nov. 



Plant stoutish, creeping, dull pale-green ; stems 1-1^ inches 

 long, 1 line wide, dichotomous, much decurved at tips. Leaves 

 opposite, close, imbricate, very regular, sub-convex, oblong, 

 falcate, dimidiate ; base twice the width of apex, sub-am- 

 plexicaul, truncate, trifid; teeth long, spreading, acute; the 

 lower sinus larger, with occasionally a minute toothlet in it ; 

 margins slightly sub-sinuous, the dorsal much arched and over- 

 lapping stem, the ventral somewhat excised with the lowest 

 portion adjoining stem wholly truncate. Cells : at lateral mar- 

 gins very minute oblong, closely compacted in longitudinal 

 lines ; larger sub-orbicular and distinct at apex ; the central 

 still larger, sub-quadrangular, and increasing in size to the base. 

 Stipules h-ee, rather large, very cellular, patent, recurved sub- 

 reuiform-quadrate, mostly 4-toothed at apex, and 1 tooth (some- 

 times 2} at sides ; cells large, of various sizes and shapes, 

 quadrangular, rhomboidal, and oblong. Flagellse numerous, 

 short, stout, and scaly. 



Hah. In forests with the preceding species, M. nitens ; 

 growing luxurianlily on clumps of Leucohryum catididum ; 1886 ; 

 W.C.
