Blunt-leaved Bog-moss - Sphagnum palustre

Description

Sphagnum palustre is rather variable in colour, forming large, untidy mats or loose hummocks that are green to yellow-brown, with or without a contrasting capitulum centre. The most distinctive plants have capitula with the centre arched above the outer part, the centre salmon-pink to brick-red or dark brown (especially in the autumn and winter), contrasting with paler spreading branches. Spreading branches in the outer part of the capitulum and just below are usually elongated and narrowly tapering. Fascicles have 2 or 3 spreading and up to 4 pendent branches. The basal part of branch leaves is usually held at an angle of less than 45° to the branch stem, though the upper part can be widely spreading to almost recurved. Capsules are occasional.
