Closely as this species resembles Sph. subsecwidum, it may be 

 immediately distinguished from it by a section of the stem, which 

 in the latter species exhibits only a single layer of sharply denned 

 cuticular cells ; in Sph. laricinum there are always two strata of these 

 cells, and not unfrequently a third more or less complete series of 

 smaller size is also present. The hyaline cells of the branch leaves 

 are larger and have fewer pores, and the inner perichaetial bracts 

 have the apex obtuse with a distinct notch ; the rarity of the fruit, 

 however, prevents the latter character being often available. 

 Angstrom seems to have confused the plant with Sph. intermedium, 

 as he describes the chlorophyllose cells as trigonous, and free on 

 the dorsal surface of leaf. 



Var. ^6. teretiusculum, Lindb. 



Stems slender, with large oblong, obtuse leaves, somewhat 

 fringed or toothed at apex. Branches crowded, terete, incurved, 

 or more or less circinate ; branch leaves short, very broad, concave.

 cundum var. contortum.
