1 6. Sphagnum Lindbergii, Sciiimper. 



Pl. XXIII. 



Monoicous ; glossy yellowish green tinged with reddish brown, 

 the stem with 3-4 layers of cuticular cells. Stem leaves auricled, 

 broadly Ungulate ; the apex broadly truncate and fringed. 



Branch leaves in five rows, not undulated, ovato-lanceolate, 

 toothed at apex ; the chlorophyllose cells elliptic, enclosed by the 

 hyaline, but nearest the back of leaf. Perichsetia large, inflated ; 

 bracts oblong, truncate and fimbriate at apex.

Sp/i. cuspidatinn, Lindr. in Bot. Notiser, 1856, p. 122. 



Sph. cuspidatim li.fulviaii, and Sp/i./it/vum, Sendtner, Mss. 



Monoicous ; growing in large dense tufts, glossy yellowish 

 green, tinged with ferruginous or purplish brown. 



Stems 6-12 in. high, solid, dark brown; the peripheral cells 

 rufous red, not much thickened ; the cuticular cells irregular in 

 size, without pores, forming 3-4 strata. Stem leaves crowded, 

 reflexed, broadly Ungulate, auricled ; the apex broad, transversely 

 truncate and fringed ; basal cells hexagonal, in four rows, pale 

 brown, then becoming narrow and elongated, with a few imperfect 

 fibres in the lateral cells, these narrow cells bound a central 

 triangle, the base of which is formed by the apical margin, and 

 this space is occupied by large, loose, rhombic cells, broader and 

 2-3 partite at the apex of leaf; without fibres and pores, both of 

 which occur sparingly in the auricles. 



Ramuli 4-5 in a fascicle, 2-3 arcuate, divergent, the others 

 pendent, elongated, and closely appressed to the stem ; retort cells 

 of the branches larger, recurved at apex. 



Leaves of divergent branches numerous, in five ranks, firm, not 

 undulated, rather glossy, brownish or ferruginous green, ovate at 

 base, becoming lanceolate above, toothed and involute at ?pex ; 

 hyaline cells elongated, with numerous annular and spiral fibics, 

 and many minute pores at margin ; chlorophyllose cells narrow, 

 elliptic in section, quite enclosed but nearest to back of leaf; border 

 widest at base, formed of 3-4 rows of very narrow cells.
