very long. Capsule suberect, arcuate, cylindric, smooth, 

 rarely sulcate ; lid with a long slender rostrum ; calyptra 

 long, cucuUatc ; peristome orange to red, confluent below, 

 cleft above into two unequal subulate, articulate legs. All 

 Tasmanian forms have a narrow pale leaf border, and are 

 often placed in the genus Leucolorna. 



This genus may be known by its robust structure. From 

 Campylopus it may be readily distinguished by its naiTow 

 nei've, straight seta, and plain base of the calyptra. 



Margin spinulose. Nerve furrowed polysetum. 



Margin serrate. Nerve solid. 



Leaves broadly lanceolate pungens 



Leaves long filiform Menziesii 



Margin with few or small serrations. Nerve nari'ow, 

 fiat. 



Leaves brittle, serrations close setosum 



Serrations irregular Billardieri 



Leaves narrow, serrations spinulose... robustum 



Margin entire. 



Leaves slender intcgerrimum 



Leaves ovate eucamptodontoides 



DICRANUM POLYSETUM, Hampe. 



Robust, rigid, suberect, sparely branched, 6 cm. Leaves 

 squarrose, sometimes subsecund, plicate, tapering to a slen- 

 der apex, lower margin plain hyaline, upper margin and 

 nerve spinulose dentate, 9 m.m. ; nerve continuous, fur- 

 rowed, with two prominent ridges; cells linear, those to- 

 wards the nerve nearly quadrate ; alars numerous, quadrate, 

 large ; perichaetials longer, sheathing, shortly piliferous. 

 Setas usually many in each sheath, 3 cm. ; capsule cylin- 

 dric, slightly inclined and arcuate, 2.5 m.m., base slendefr, 

 strumose. 



Common in forests. 



DICRANUM PUNGENS, H.f. et W. 



Erect or decumbent, often growing in water, and elon- 

 gated, usually black, except the tip. Leaves squarrose to 

 patent, 4 m.m. ; base long and broad, then tapering 

 to an acute apex : margin remotely serrate, except towards 

 the base; nerve round, usually dark; cells long, linear; 

 alai-s not numerous, oblong, and not in a well-defined patch.
