 POLYTRICHUM ( L'ii.poli//richa lyracliycaulia) LONGIPlLUiM, n. Sj'., 

 C Mueller, in " Hedwigi.i," vol. xxxvi., 1897. 



In very loose, glaucous-green tufts of an inch ; stem simple, 

 leafless below, bristly-leaved towards the apex. Cauline leaves 

 in an open head, when moist recurved ■ spreading, narrow 

 lanceolate-acuminate, but little twisted, distinctly recurved-con- 

 volute, with the base gold-coloured and narrowly and somewhat 

 laxly reticulate ; the margin of leaf entire and slightly rugulose 

 at the dorsal apex ; nerve broad, occupying neaily the whole of 

 the blade, elongated into a robust ferrugineous, terete, flexuous, 

 more or less indistinctly denticulated point. Cellules areolate, 

 much thickened. Perichrelial bracts with longer, filiform points. 

 Seta rather hhort, thick, somewhat rigid. Theca small, inclined, 

 verrucose, cubical, discoid-apophysate. Operculum rostrate from 

 a rather flat base. Calyptra lurid, shortly and obliquely beaked, 

 surpassing the capsule. Teeth of peristome short and narrow. 



Habitat. — Sludley Park, near Melbourne ; F. Reader, 2nd 

 August, 1883 ; forwarded from Dimboola in 1892 ; Upper Ovens 

 River, M'Cann, 1882, in Hb., Melbourne; Grampians, without 

 sj^ecified locality: Hb., Melbourne, 1881 ; Daylesford : R. 

 Wallace, 1877, in Hb., Melbourne; Fowler's Bay: Hb., Mel- 

 bourne, 1 88 1. Common in Australia. 



This species may at once be recognized by the leaves when 

 moist being patent-recurved and but little twisted. 



POLVTRICHUM {EvpolytricJLa, appressi/olia) NODICOMA, n. sp., C. 

 Mueller, in " Hedwigia," vol. xxxvi., 1897. 



In very loose ferrugineous tufts of ij/^ inch. Stem simple, 

 slender, flexuous, nearly terete ; lower part almost leafless ; male 

 flower terminal in a knotty head. Cauline leaves small, densely 

 imbricate, when moist somewhat recurved-spreading, base short, 

 rather broader, pale, narrowly and laxly reticulate ; shortly and 

 narrowly lanceolate-acuminate, much involute, remotely serru- 

 late above, nerve occupying nearly the whole of the lamina, 

 rather scabrid at the back, drawn out into a more or less long, 

 ferrugineous, rigid, terete, and rather robust point, abruptly erose- 

 denticulate at the summit. Cellules areolate, much thickened. 

 Other parts unknown, 



.^a6i/a(!,— Oakleigh. F. M. Reader, i4lh Sept., 1886. Male 

 plant only forwarded from Dimboola in 1892. 



This species differs from /'. Tisdalli in the greater height, antl 

 in the leaves being acutely, finely, and remotely denticulate.
