54 THE SPHAGNACEA OR PEAT-MOSSES OF 
concave, convolute above, very narrowly margined; the apex 
truncate, and with 5-6 irregular teeth; the hyaline cells angulato- 
fusiform, very prominent and confluent at the back, with annular 
and spiral fibres, and a few large pores; chlorophyllose cells 
slender, triangular, projecting between the hyaline at the concave 
surface of leaf. Capsules in the capitulum or upper fascicles, peri- 
chetium not separating, the upper bracts broadly oblong-ovate, 
convolute, with 2-3 irregular teeth at apex, the lower cells 
elongate hexagono-rhomboid, the upper normal, free from fibres 
and pores. 
Male amentula short, thick, purple, placed in the coma; the 
bracts oblong, obtuse.

Professor Lindberg was the first to identify Sp. Miller with 
the American Sp. molle, and undoubtedly they only constitute a 
single species, yet, as certain differences exist between them, I 
have deemed it best still to maintain Sph. Miilleri as a variety. 
Taking the original plant issued in the Muscz A lleghanienses as 
the type, it presents a different aspect to Sph. Miilleri in that its 
branch leaves are shorter, broader, more divergent, and slightly 
squarrose, the stem leaves without fibres in the lower half, and the 
plants more rigid and of a greener colour. The specimens are 
without fruit, but, according to Sullivant’s figure, the apex of the 
perichetial bracts is truncate and not acutely acuminate. As to 
the dioicous position of the inflorescence, it is probable that some 
error exists, as in Sph. Miilleri the male amentula are certainly very 
rare, and appear to be of short duration ; I have observed them in 
specimens received from Mr. Sim, and in these they were very 
short, and of a rich purple colour. 
That Sullivant did not clearly understand his plant is evident, 
as, in his two Exsiccata, forms of Sp. molle are referred to four 
different species.

elongated, the hyaline celis strongly fibrose and porose except near
