i-1 inch apart, stoutish, usually simple, (sometimes once 

 branched, branch patent, horizontal,) 2 inches high, 4 lines 

 wide, flexuous, succulent, decurved, pale-green, the base of stipe 

 bare with small distant leaflets above increasing in size up- 

 wards to the leaves. Leaves, sub 20 pairs on stem, alternate, 

 pinnate, close-set, imbricate, wavy, somewhat quadrilateral- 

 elliptic, apex truncate, rounded, and slightly retuse, sub-sessile, 

 attached to stem only at posterior corner, slightly decurrent, 

 tips and margins sub-recurved, closely serrulate on anterior 

 margin, apex, and upper half of posterior margm, remainder 

 entire; anterior margin arched, posterior nearly straight, the 

 entire portion thickened ; teeth iri'egular in size, broad at base, 

 2-3 cells in each ; colour clear dark-green ; cells various, 

 oblong, triangular, etc., scattered ; cell-walls thick, double. 

 Involucre terminal, vertical, pendulous, cylindrical, 3 lines long, 

 very narrow, obtuse, light-green, covered with a fine, minute, 

 light-reddish scaly scurf. 



Hab. On rotten logs, growing in large compact patches, in 

 wet shaded forests near Norsewood ; 1885-8G : W.(J. 



Obs. This species has close affinity with T. saccata, [Gyin- 

 nanthe of " Handbook N.Z. Flora," and of " Species Hepati- 

 carum,") but differs from it in its smaller size, more numerous, 

 larger, closer, imbricate and wavy leaves, which are also of a 

 different shape, as are also their cells, their margins more denti- 

 culate, and only adhering by the lower corner to the stem, and 

 in its furfuraceous torus. I have very rarely found it in a 

 fruiting state, and then only after long and diligent search. 



2. ? T. perpusillus, sp. nov. 



Plant very small, delicate, pale-green ; rhizome creeping, 

 short, very slender. Stems erect, ^-f inch high, densely com- 

 pact and gregarious, slender, sub-succulent, simple, flexuous, 

 slightly thickened at tips, 1 line wide including leaves, usually 

 leafy to base. Leaves minute, alternate, usually distant, (some- 

 times close and sub-imbricated at the middle,) pinnate, mostly 

 12-14- (rarely 20-) jugate, sub-quadrate-orbicular, truncate, 

 deeply notched or sub-bihd, the upper lobe larger, apices acute, 

 sinus very broad, sometimes minutely toothed, sessile, clasping, 

 shghtly decurrent, a little twisted and convex, patent, margius 

 entire ; anterior margin arched, slightly uneven at apex ; pos- 

 terior straight, or slightly excised at base. Cells minute, 

 crowded, sub-orbicular, their walls thickened, with scattered 

 very minute cellules within them. Fruit not seen. 



Hub. In shady damp niches, in the summit or peak of a 

 high hill named " Cook's Tooth," near Porangahau, County of 

 Waipawa ; 188G : Mr, H. iJUl. 



Obs. A species having affinity with the preceding, T./ur- 

 /uraceus, Col., to which it bears a striking general resemblance,
