recurved, especially from the middle upwards. Perichaetial
leaves nerveless, ovate below, the upper portion spreading,
suddenly acuminated into a long hair-like point. Fruit-
stalk smooth and shining. Capsule smaller than in most
of the allied species, ovate, moderately cernuous and occasionally
a little curved. Peristome reddish; outer teeth
slender; inner peristome pale yellow, somewhat shorter,
divided halfway down into 16 lanceolate pervious segments
; with intermediate pairs of cilia half as long. Operculum
reddish, conical, tapering, very acute, half as long as
the capsule.
H. lutescens, an allied species, has a rough fruitstalk and
a blunt shortly rostrate lid, with closely imbricated and erect
leaves. H . nitens has leaves considerably narrower, truly
awl-shaped. Perhaps it is more closely allied to H . albicans,
but the leaves in that species, though similar in shape
and somewhat serrulate at the edges, are only very faintly
marked with two lateral striae, scarcely visible when dry;
and they are more crowded and erect.—W. W.
