wide, with scarcely thickened walls and extending in a 
broad band across the leaf base, the widest cells toward 
the costa; inner perichaetial leaves ecostate, erect, 2.5 mm. 
long, gradually narrowed to a lanceolate, serrulate point; 
seta smooth, 2 cm. long; capsule erect, ovate-cylindric, 
about 2.5 mm. long without the lid, the exothecal cells 
with quite evenly and slightly thickened walls, 15-20 4 
wide by 30-50 w long, the stomata abundant, in 4-5 rows 
at the base; lid with slightly oblique beak rather over one 
third the length of the rest of the capsule; annulus none; 
outer peristome of pale, lanceolate teeth about 250 » high, 
with prominent oo on the outer face and plates 
finely papillose to near the base, the basal plates close 
together and ai inner peristome a very papillose 
irregularly incised margin scarcely forming segments; 
calyptra extending well down the capsule, bearing scat- 
tered, iar hairs on the basal half; spores minutely 
roughene , 16 w in diameter

This plant looks much like and perhaps stands nearest 
to Homalothecitum tokiodense (Mitt.) Besch. P. appressi- 
foltus differs in having the points of the leaves broader and 
shorter, the cells of the leaf-base larger with thinner walls 
and the peristome-teeth broader in the upper part with the 
joints less prominent. I may add that I do not think 
Homalothecium is in any way distinct as a genus from 
Pleuropus. (Plate 174.)

At once distinguished from the preceding by the spread- 
ing leaves, the longer leaf-point, the leaf-base of elongate, 
narrow cells toward the costa, also by the shorter pedicel 
and striate teeth of the peristome.
