scheme according to Dr. Warnstorf except that varieties 

 and forms are not included : — 



Tasmanian forms belong to four sub-sections of the genus, 

 namely, Cymbifolia, Rigida, Cuspidata and Subsecunda. 



Sub-section Cymbifolia. Robust; leaves concave, obtuse, 

 dentate at the back of the apex, tracheids about 40-60/* 

 in diameter ; cortex of the branches, and sometimes the 

 outer series of the stem cortex bearing spiral fibres. 

 Chlorophyllous cells narrow, small, elliptic, generally cen- 

 tral. 



Stem coi*tex with fibre cymhi folium. 



Stem cortex without fibre. 



Stem leaves with fibres, branches long, slender 



maximiiin. 



Stem leaves without fibres, branches short, rigid 



, subbicolor. 



Sphagnum cymbifolium Ehrh. 



Robust, the divergent branches about 3 cm., tapering to 

 slender tips. Stem cortex broad in 3-4 series, superficial 

 cells with fibres and round pores, sclerotic ring brown, 

 thin, pith broad. Stem leaves ligulate, veiy obtuse, 2.7 

 mm. Lower leaves of divergents broadly ovate, obtuse, 

 concave, apex incurved dentate on the dorsal surface, 2.5 

 mm., border very narrow, tracheids short and broad, those 

 towards the apex and margin with many large oblong 

 pores; cells narrow elliptic, the wall exposed on the upper 

 surface, enclosed on the lower ; upper leaves longer. Branch 

 cortex cells very inflated, copiously fibred. 



Kingston, Near Lake Sorell, Western Tiers. 



Sphagnum maximum Wamst. 



Pale, slender, long, the divergent branches spreading, 

 tapering 2-3 cm. Stems cortex broad 3-4 cells, without 

 fibres, sclerotic ring brown, thin, pith broad. Stem leaves 

 broadly ligulate, very obtuse, 1.5 mm., tracheids with spiral 

 iibres. Branch cortex inflated, fibred. Branch leaves very 

 broadly ovate, concave, obtuse, 3 mm., border very narrow, 

 apex cuspidate on the back, tracheids short and broad, 

 pores large oblong, numerous, irregularly disposed, upper 

 leaves narrower and longer ; cells very small, narrow 

 elliptic, central. Very close in structure to S. subbicolor. 



Native of New Zealand. Recorded also as Tasmanian be- 

 cause found as packing in an apple case said to have come 

 from Tasmania. No locality known.
