21. Glyphomitrium latifolium, Broth., n. sp. 



In somewhat dense tufts, easily falling to pieces, dark 

 green, not at all shining. Stem to 2 cm. high, erect, 

 flexuous, radiculose at base, densely leaved, simple or 

 dichotomous. Leaves when dry crispate-appressed, when 

 wet reeurved-patulous, carinate-concave, from a scarcely 

 dilated base oblong, rotund-obtuse, c. 3 mm. long and c. 

 0'85 mm. wide, margins erect, quite entire, slightly undulate ; 

 nerve rufescent, somewhat thick at base, gradually narrowing 

 above, vanishing below the apex ; cells rotund, c* 0-010 mm., 

 the basal minute, quadrate, the intramarginal forming a 

 lutescent border composed of from 4 — 5 series of rectangular 

 cells, the intralimbate smaller, rectangular, less incrassate. 

 The rest unknown. 



Hab. — New Town Eivulet, on water-washed rocky bank, 

 W.A.W. Nos. 1484, 1891, 1896. 



_ " A very distinct species," says Mr. Brothems, " readily 

 distinguished by the form of the leaves." 



22. Macromitrmm (Goniostoma) weymouthi, Broth., n. sp. 

 Slender, prostrate, interwoven, bright-green, finally 



ferruginous. Stem longly creeping, vaguely branched ; 

 branches crowded with short, straight, or somewhat curved 

 branchlets, densely leaved. Leaves when dry appressed, 

 incurved at apex, spirally twisted, when wet erecto-patent, 

 oblong-lanceolate, acute, the lower margins more or less 

 revolute, quite entire. Nerve lutescent, vanishing below the 

 apex; the basal cells elongate, very incrassate, and their 

 cavities very narrow, those above the middle of leaf rotund, 

 very incrassate, their cavities very minute, all pellucid and 

 quite smooth. Perichaetial bracts erect, larger, acuminate. 

 Seta erect, curvate-flexous, 8 — 15 mm. high, yellow, quite 

 smooth; capsule erect, oval, plicate when empty, small 

 mouth, dull brown ; peristome simple, the teeth arising below 

 the orifice, short, papillose ; operculum rostrate, the beak

Hab. — On wood, Porteus Gully, Queen Biver Boad, 

 Macquarie Harbour, and also Heiity Biver, on branch of 

 myrtle, 1891, W.A.W., Nos. 573-5, and 569. 



" Nearest to M. scottim, C. Mull., but at once separated by 

 the acute leaves, the vanishing nerve, and also the smaller 

 cells." 



23. Macromitrium C Gonio stoma) tasmanicum, Broth., n.sp.
