CAMPYLOPUS INSITITIUS, H.f. et W. 



Densely tufted, stems commonly very slender, erect, 

 simple, yellowish-green, 3-5 cm. Leaves involute, lanceolate, 

 tapering to a slender plain point, but sometimes tipped with 

 a short cuspidate hyaline hair, 4 m.m. ; nerve shallow, but 

 two-thirds the breadth of the leaf ; wings lost far below the 

 apex; cells irregularly rhomboid, larger, less incrassate, 

 and more opaque than those of C. capillatus, a narrow band 

 of linear cells on the margin continuous with the large rec- 

 tangular basal cells; alars delicate, colourless, quadrate, 

 usually forming distinct auricles. Seta 5 m.m. ; capsule cyl- 

 indric, inclined, 1.2 m.m.; lid with a rostrum nearly as 

 long. 



Kingston, Macquari© Harbour. 



Variable. On sandy heaths often very short, dispersed, 

 leaves broader, with a hyaline point. On wet button -grass, 

 Southport, similar, but quite black. Best distingnished by 

 the shape of the cells.

 yellow, black below. Leaves broadly lanceolate, tapering 

 into a slender point, usually cuspidate hyaline at the ex- 

 treme tip, 5 m.m., with small auricles, wing vanishing far 

 below the apex ; nerve less than half the breadth of leaf ; 

 cells very irregularly rhomboid, those towards the basie 

 quadrate ; alars brown, quadrate, incrassate. E-est not seen. 



Port Arthur. 



CAMPYLOPUS TORQUATUS, Mitt. 



Caespitose, light green, usually under 1 cm. Leaves 

 very slender from a short sheathing base, tapering to an 

 acute, not hyaline, point, 5 m.m. ; nerve shallow but very 

 broad, constituting nearly all the breadth of the leaf ; cells 

 rectangular, short above, longer and colourless below. 

 Seta 7 m.m.; capsule narrow, oblong, straight, 1.2 m.m.;
