branch leaves have very minute papillae on the internal wall of the 

 hyaline cells, where united to the chlorophyllose. 



12. Sphagnum fimbriatum, Wilson. 

 Pl. XVI. 

 Monoicous ; slender, pale whitish green ; cuticular cells of stem 

 in 2-3 strata. Stem leaves large, broadly obovate-spathulate ; the 

 margin in the rounded upper half laciniate-fimbriate ; border of 

 narrow cells one-third the width of leaf at base, disappearing half- 

 way up the leaf. Branch leaves ovato-lanceolate, the chlorophyllose 

 cells compressed, enclosed, but nearest upper surface of leaf. 

 Pericheetial bracts obovate-oblong, obtuse, emarginate. Male 

 amentula fusiform.

Monoicous ; in loose, pale whitish-green or glaucous-green tufts. 

 Stem very slender, 6-14 in. long, pale green, with 2-3 layers of 

 rectangular, porose, cuticular cells, those of the peripheral layers not 

 coloured. Stem leaves large, erect, broadly obovate or obovato- 

 spathulate, the margin in the rounded upper half laciniate-fimbriate ; 

 hyaline cells of the middle and upper part rhombic, with one 

 or more partitions, and without fibres or pores ; chlorophyllose 

 cells long, linear, forming a border which occupies one-third the 

 width of base, but rapidly narrows and disappears half-way up the 

 margin. 



Ramuli 3-4 in a fascicle, very long, attenuated, two arcuate, 

 decurved, the others pendulous, filiform. Lower ramuline leaves 

 broadly ovato-lanceolate, upper elongate, lanceolate, acute, with a 

 narrow border ; hyaline cells with annular and spiral fibres, and a 

 row of large pores on each side ; chlorophyllose cells compressed, 

 enclosed by the hyaline, but nearest the upper surface of leaf. 



Capsules at first immersed in the large imbricated perichsetium, 

 afterwards becoming moderately exserted ; lower bracts obovate-
