144 NORTH AMERICAN FLORA [VoLumy 15 
lower 4 mm., the upper about 7 mm. long; costa up to 200 » wide near the base, somewhat 
rough on the back above, excurrent into a terete, dentate point, in cross-section about halfway 
down showing a ventral row of large cells, a median row of cells nearly as large, and a stereid- 
band on the dorsal side; alar cells reddish to hyaline, often much inflated, those next above 
more or less pale, laxly rectangular within, gradually smaller toward the margin, soon becoming 
smaller upward, with thickened, colored walls, the leaf-blade very narrow one half up with 
narrow cells 3-5 times as long as wide and the margin serrulate to the apex.

Plants in rather rigid, compact tufts, greenish or yellowish above and brown or black- 
ish below; stems erect, tomentose below, 1-7 cm. high, with leaves appressed or erect- 
spreading and rather uniformly placed along the stems or comose at intervals: stem-leaves 
narrowly lanceolate to oblong-lanceolate, ending rather abruptly in a few hyaline teeth or 
extended into a more or less elongate, denticulate, hyaline point often geniculate at the base 
when dry, the gradually narrowed leaf-blade scarcely extending to the base of the hyaline 
point and entire or nearly so; costa 300 » wide or more near the base, about one half to three 
fifths the width of the lower part of the leaf, with more or less serrulate lamellae up to 3 cells 
high on the back extending to below the middle of the leaf, in cross-section below showing a row 
of ventral cells extending about two fifths through the leaf, and a median row about one half 
as large, with a stereid-band below; alar cells from rather inconspicuous to inflated and from 
reddish to hyaline, the cells next above more or less narrowly rectangular, thin-walled and 
hyaline, those higher up somewhat thick-walled, colored and short-rhomboidal to obliquely 
oval; inner perichaetial leaves with a convolute blade extending nearly to the base of the more 
or less elongate, hyaline, rough point: seta 6-9 mm. long, sinuous, rough near the capsule: 
capsule not quite regular, oval, rugose at the base, furrowed when dry, with the lid obliquely 
short-rostrate; peristome-teeth reddish-brown, 45-60 « wide at the base, split about half way 
down from the apex: calyptra ciliate at the base: spores rough, up to 13 w in diameter.
