cells sometimes pitted. Capsule with’lid up to 2.5 mm. long. 
Sporangium oblong, scarcely or not contracted below mouth 
and rather abruptly narrowed when dry to the shorter col- 
lum. Peristome yellowish below, the lower plates of teeth 
mostly twice wider than high, gradually becoming nearly 
square above; lamellae 16-18, irregularly connected by 1-3 
cross walls between adjoining lamellae; segments narrow 
and narrowly perforated, separated by mostly 2 cilia, a little 
shorter and often long appendiculate. Annulus broad, of 3 
rows of cells. About 3 rows of transversely elongated cells 
about mouth of capsule, the cells near middle becoming some- 
what rectangular and in collum scarcely elongated and sin- 
uous walled, with oblong stomata about .o4o mm. long. 
Spores smooth or nearly so, up to .025 mm. (Plate 17.) 
Dawson, on damp earth. In good fruit Aug. 28, 1898. 
This plant is undoubtedly close to pendulum differing in the 
short pointed leaves, more distinctly bordered and in the long 
cilia, some of which are finely appendiculate (585). 
M. Philibert left me in doubt as to just what he considered 
this plant and I have finally ventured to describe it as a dis- 
tinct species rather than a variety of pendulum. 
Bryum longisetum Bland. Dawson. In good fruit July 
31, on swampy ground with Meesea uliginosa. These 
specimens have a seta up to 8.5 cm. high. The teeth are 
small with only about 12 lamellae not joined by cross walls, 
the dorsal plates high (about 1 to 2). Inner peristome free 
with narrow segments and very short cilia. Spores large 
and nearly smooth, up to.og4o mm. Leaves long-pointed, 
costa excurrent for a length of 4 or 5 cells (649). 
Bryum conditum R. S. Williams, sp. nov. 
Dioicous. Male plants discoid. Tufts up to 3.5 cm. 
high. Stems and branches more or less radiculose. Outer 
perichaetial leaves oblong-lanceolate, with a gradually nar- 
rowed base, up to 4.5 mm. long. Upper stem leaves a 
little shorter with broader base, all entire, with costa 
excurrent for a length of 3 or 4 cells and a brown revolute 
border of thick-walled cells in double layer, confluent with 
the costa. Lower stem leaves much smaller with costa van- 
ishing. Inner perichaetial leaves very broad, the width very 
often equal to }, or more, of the length and costa percurrent.
