EUROPE AND NORTH AMERICA. 63 



branch leaves have very minute papillce 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. 

 Perichaetial 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 bordci 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. fj 



Capsules at first immersed in the large imbricated perichcetium, 

 afterwards becoming moderately exserted ; lower bracts obovate-
