rank, but also to that of a separate section in the genus, as indicated 
by Professor Lindberg under the appropriate title of emitheca. 
The var. sedoides bears the same relation to the type as the var. 
cyclophyllum does to Sph. laricinum. Perhaps the most singular 
feature of the plant is the very small capsule, which appears to 
have been overlooked until collected by Austin, and even when 
present, some care is required before it can be detected, so com- 
pletely is it concealed by the perichzetial bracts. 
Sect. III.—Isoctapus, Lindo. 
Plants whitish, glossy, resembling some species of Leucobryum, 
rigid, fragile. Branches acute in distant fascicles of 2-5, all 
arcuato-divergent, subclavate. Branch leaves very large, accrescent, 
distant, spreading, lanceolate; the cells very narrow, serpentine, 
without fibres, but with a central longitudinal series of pores. 
Perichztial bracts divergent, resembling the leaves in structure. 
20. Sphagnum macrophyllum, Brrnuarpt. 
PL. XXIX. 
Dioicous ; pale olive green, glossy, shining. Branches uniform, 
divergent, lax-leaved. Stem leaves minute, ovate-oblong, obtuse. 
Branch leaves narrowly lanceolate-subulate, toothed at apex ; 
hyaline cells narrow, elongated, without fibres, and with 6-10 pores 
in a longitudinal median line ; chlorophyllose cells circular, separating 
the hyaline both in front and back.
