LEPTOSTOMUM, R. Br. 



Robust and soft, sparely branched, covered, except 

 the apex, with close, purplish-brown tomentum, binding 

 the stems into a dense cushion. Leaves rather rigid, broad, 

 ovate, or oblong, usually obtuse, witli a long, hair point ; 

 nerve slender, excurrent, cells small, rotund or subquadrate, 

 strongly incrassate. Capsule on a tall, terminal seta, 

 clavate, pyriform, with a tapering neck, and constricted 

 mouth ; lid small, hemispheric. Peristome single, a short, 

 irregular membrane. 



L. macrocarpum, R. Br., which differs from L. in- 

 clinans principally by the terminal hair being branched, has 

 been recorded as Tasmanian, but probably erroneously. 



Leaves obtuse or shortly acuminate inclinans 



Leaves very obtuse or emarginate gracile. 



LEPTOSTOMUM INCLINANS, R Br. 



Pale green, robust, in dense cushions, stems 2-5 cm. 

 Leaves erect, imbricate, ovate, oblong 2.5-3.5 m.m. ; apex 

 usually obtuse, sometimes shortly acuminate, usually with 

 a few irregular teeth in the upper portion ; nerve slender, 

 excurrent in a slender, jointed hair. Seta, 2-4 cm. ; cap- 

 sule inclined, narrow pyriform, with a tapering neck, 5-7 

 m.m., mouth contracted. 



Forms with an acuminate apex and dentate margin 

 have been referred to L. Menziesii Hook, an African 

 species, which probably does not occur in Australia. 



Common on wood in forests. 



LEPTOSTOMUM GRACILE, R. Br. 



Bright green, in small, loose mats; stems seldom ex- 

 ceeding 2 cm. Leaves patent, ovate, L5 m.m., very ob- 

 tuse, emarginate; margin plain, recurved; nerve slender, 

 excurrent, in a short, jointed hair. Seta 2 cm. ; capsule 

 inclined, narrow pyriform, with a tapering neck, 4 m.m., 

 constricted below the narrow mouth.
