O u R specimens of this uncommon moss, were gathered in
Anglesea by the Rev. H. Davies, bearing ripe capsules in May.
Mr. G. Don has found the same species near Forfar, Angus-
shire, and Mr. Turner in Ireland.
The roots are annual. Stems simple, forming dense tufts,
scarcely half an inch high, leafy. Leaves of a light, often
brownish, green, strongly reticulated, slightly spreading, elliptic
lanceolate, acute, flat, or somewhat carinated, with a
prominent rib. Their margin minutely serrated about the
point only, sometimes entire throughout, especially in the
inner leaves. Fruitstalk solitary, terminal, about an inch
long, yellow when young with a reddish base, at length
brown. Capsule upright, brown, smooth, cylindrical with
a widish mouth. Lid taper, oblique, rather shorter than the
capsule, springing from a flat basé, and attached by its centre
to the columella, which, as usual in the genus, rises above
the edge of the capsule.
