No one but Mr. Dickson seems to have kn'own this
moss, till from his Scottish specimens, and the account
published by himself, a description of it appeared in the
Flora Brilannica. Our liberal friend Mr. Winch has lately
communicated it from Northumberland. It bears fruit in
July and is perennial, growing on turfy bogs.
The stems form tufts an inch or two in height, and are
more or less branched. Leaves of a dull darkish green, closely
imbricated, straight, lanceolate, broadish, acute, keeled; dilated
and entire at the base; serrated near the point. Fruit-
stalk terminal, solitary, various in length, wavy, curved at
the top, red. Capsule pendulous, turbinate; when ripe of a
rusty brown, with a wide mouth. Lid convex, with a little
blunt point. Fringe yellowish.
