T h i s elegant moss is a native of alpine bogs. It was known,
without fructification, to Richardson and Dillenius; but the
capsules were first discovered in Yorkshire and Cheshire by
Mr. Bradbury, who sent them a few years since to Mr. Dickson.
Gur specimen was gathered at Beddgelart, North Wales,
by Mr, D. Turner in July 1802.
The stems are perennial, erect, leafy, clothed with dense
rusty pubescence, and divided,irregularly into various spreading
branches. Leaves imbricated, spreading, of a yellowish shining
green, lanceolate, pointed, evidently, though finely, serrated,
furnished with many lateral ribs or nerves besides the
principal one. Stalks solitary, at first terminal, but by the
branching of the stem above them they soon become lateral;
they are short, red, recurved, with a few small scales at their
base. Capsule drooping, globose, green and smooth when
young, but brown and marked with 16 furrows when ripe.
Lid red, convex with a blunt point. Outer fringe shortish,
red; inner white and very thin, with 16 teeth.
