42 THE SPHAGNACEJ5. OR PEAT-MOSSES OF 



This variety is not so frequent as the typical form, into which 

 it gradually passes, and the stem leaves have usually their apical 

 cells fibrose, and with one or two large pores. It sometimes grows 

 intermixed with the true Sph. squarrosum, as in the specimens from 

 Sutton Park, issued in my Exsiccata. 



Group B.— SUBSECUNDA. 

 Plants soft, slender. Branches terete, their cuticular cells empty ; 

 branch leaves erecto-patent or somewhat imbricated, usually sub- 

 secund, ovate, rather obtuse with the apex truncate, the margin 

 involute in the upper half. 



5. Sphagnum tenellum, Ehrhart. 



Pl. VI. 



Dioicous, slender, extremely fragile, pale greenish yellow, the 

 stem with two layers of cuticular cells. Stem leaves ovate-oblong, 

 with a broadish border of narrow cells. Branches with laree 

 retort cells recurved at neck ; branch leaves ovato-lanceolate, 

 3-toothed at apex, with a broad border ; hyaline cells porose on the 

 upper surface, reticulate-fibrose ; chlorophyllose cells triangular, 

 interposed between the hyaline at back.
