REQUENT in moist sandy places, but usually barren.
Our specimen was gathered in Winwick Stone Delpli, near
Warrington, in May 1833.
Fertile stems very short. Barren shoots longer, bearing
club-shaped fingered gemmae in the axils of the
leaves (figured by Hedwig, and marked a. a. in his plate).
Leaves on the fertile stem smallest at the base, where they
are ovate, gradually longer and narrower higher up, uppermost
linear-lanceolate, yellowish green, entire, except
at the very summit, nerved throughout, margin slightly
recurved. Perichaetial leaves longer than the rest, with
more strongly recurved margins, serrulate towards the
apex. Leaves on the barren shoots rather distant, moderately
spreading, narrowly ovate, nerve ceasing below the
apex. Fruit-stalks very pale and rather succulent. Capsule
more or less pendulous, oblong-pyriform, gradually
