256 TASMANIAN BRYOFHYTA, 



R.S. TAS. 



large as tracheids obtusely wedge shaped, the convex base 

 free on tlie external surface. 



Macquarie Harbour, Mt. Wellington. 



Sphagnum trichophyllum Warnst. 



Medium sized, generally submerged, densely fascicled, 

 with rather long flaccid branches. Stem, cortex 1-2 series 

 of small cells, wood cylinder ill-defined, stem leaves trian- 

 gular, 1.3 mm,, apex sub-acute, obscurely cuspidate, border 

 broad but the linear cells not much altered from the 

 tracheids, cells as broad as the tracheids, lower tracheids 

 narrow without fibres; branch leaves linear elongated to 

 a slender truncate cuspidate or acute apex often 6 mm. 

 long, margin with a border of 3 linear not much narrowed 

 cells, margin cuspidate, tracheids with few or no fibres or 

 pores, mostly under 10^ diameter. Iti transverse section 

 the cells nearly as broad as the tracheids and nearly round. 



Common in water. 



Sphagnum Brotherusii Warnst. 



Slender, fascicles not verj'' distant 4-5 branched, the 

 divergents not distinct from the pendants, 3-4 cm., slender 

 and tapering. Stem cortex of 2-3 series of small thin 

 walled cells, woody cylinder distinct; stem leaves narrow 

 triangular, 2.3 mm., border broad below, narrow and indis- 

 tinct above, apex small truncate, cuspidate; tracheids 

 long, lower ones without fibres ; cells nearly as wide as the 

 tracheids. Branch cortex a single series of but slightly in- 

 flated cells; branch leaves linear with a slender apex about 

 4 mm., border of 2 series of linear cells, margin cuspidate, 

 apex in the lower leaves truncate cuspidate, in the upper 

 leaves acute ; tracheids long, broad, usually 25-30/w dia- 

 meter, freely fibred, pores very few, rather large at the 

 lateral angles or none, cells one-third as large as tracheids, 

 wedge shaped with obtuse apex and convex base, base free- 

 ly exposed on external surface. 



Very similar in appearance to S. trichophyllum. 



Table Cape. 



Sphagnum drepanodadum Warnst. 

 Slender, tall, divergent branches 3-4 slender falcate. 

 Stem cortex one celled, woody cylinder very indistinct; 

 stem leaves concave, ovate-triangular from a broad base, 

 1.5 mm., apex slightly truncate cuspidate, lower tracheids 

 without fibres. Branch leaves linear tapering to a slender 

 apex, the middle ones about 4 mm., margin with a narrow 

 3 celled border, remotely cuspidate, apex truncate cus-
