180 TASMANIAN BKYOPHYTA 



R.S. TAS. 



Leaves lanceolate, elongating round the inflorescence; nerve 

 bold; cells narrow to linear, broader towardsi the base. Cap- 

 sule pendulous, clavateHpyriform, with a shoitly tapering 

 neck. Peristome as in Brijurn. Often included in Brynm. 

 Differing in shape of cells and not innovating from the top 

 of fertile stems. 



Pohlia nutans (Schreb). Lindb. 



Stems short, erect, usually under 1 cm., new branches 

 spring low down the stem, that is, not close below the 

 fertile apex. Leaves broadly to narrowly lanceolate, taper- 

 ing to an acute apex, erect, mostly 3 mm., margin coarsely 

 or obscurely serrate, not bordered, revolute in the middle, 

 nerve lost in the apex in lower leaves, excurrent in the 

 upper ones, cells long, nearly linear, strongly incrassatei. 

 Seta terminating the stem, long, slender, 3-4 cm., capsule 

 pale reddish yellow, cernuous or pendulous, 3-4 mm., narrov7 

 23yriform or nearly clavate, narrowed into a slender neck 

 below, constricted below the mouth, broadest below the 

 middle. Lid rather broad hemispheric, apiculate. 



Very common. 



Pohlia cruda (L.) Liudb. 



Rather robust, branches often 3-6 cm., slender. Leaves 

 shining, ovate to ovate^lanceolate, acute, :2.5 mm. ; nerve 

 lost at a distance from the apex ; margin remotely serrate ; 

 cells long, vermiform. 



In and about streams on plateau of Mt. Wellington. 

 Barren specimens only. 



Leptobrytjm Wils. 



Small, erect, stems simple or with few branches arising 

 only from the base. Leaves narrow, flexuous-subulate with 

 a broad nerve; cells nearly linear, broad towards the base. 

 Capsule pendulous with a long neck, narrow pyrifonn ; ^evi- 

 stome well developed, as in Bryum. 



Leptobryum fy^nforme Br. et Sch. 



Pale yellow-green in silky masses, stems usually under 

 1 cm. Leaves chiefly on tlie ends of the branches, filiform, 

 flexuose, 5 mm., flat, formed of a broad nei-ve except at the 

 sheathing base, margin serrate at apex. Seta slender, 2-4 

 cm. ; capsule inclined or pendulous, broadly pyriform, sud- 

 denly contracted below into a long slender neck, 2 mm. ; 

 lid broadly pyramidal.
