LEPIDOZIA SPHAGNICOLA, n. sp. Dioicous, densely cespitose, 
brownish-green varying to pale green; stems suberect, irre- 
gularly pinnate above, obtuse or very rarely terminating in a 
leafless flagellum; in transverse section orbicular, 6 cells in 
diameter, cortical cells about 12-seriate, slightly convex out- 
ward, about the same size as the inner cells, but with thicker 
walls; lateral branches short, leafy, usually obtuse; postical 
branches, when present, flagellate, hyaline, leafless, radiculose ; 
tadicles fasciculate, few in number in the upper part of the 
plant, simple or irregularly branched, sometimes ending in a 
spheroidal expansion especially on the flagella; stem-leaves 
mostly distant, transversely inserted, quadrate, deeply 4-parted 
to within about 2 cells of the base, sinuses narrow, lobes 
subequal, lanceolate, strongly incurved, ending in a single cell 
and from 2 to 4 cells wide at base, usually entire, but sometimes 
bearing a small tooth (composed of from 1 to 3 cells) on the 
antical leaf-margin near the base; branch leaves similar to the 
stem-leaves, imbricated, more rarely bearing an antical tooth ; 
stem-under leaves rectangular, subequally 4-parted to within I 
or 2 cells of the base, lobes subulate, 1 cell broad at the apex 
and usually 2 cells broad at the base; branch-under leaves sim- 
ilar to those of the stem, but usually smaller and only twice or 
thrice divided, with one of the lateral lobes longer and broader 
than the others; perianth terminal on a short postical branch 
given off from the lower part of the stem; bracts in 3 to 5 
rows, those of the outer rows small, irregular in shape, usually 
bifid, ciliate, those of the inner 2 rows much larger, extending ©
