An extremely variable species that is hard to distinguish from other species in this section. Some forms have curved prickly-looking branches - 'cow-horns' - but atypical forms occur.  The spreading branches are clearly differentiated from pendant, unlike the very similar S auriculatum (denticulatum).  Microscopic examination will be needed for confirmation of some specimens.

It is in Section Subsecunda, characterised by stem leaves that are spreading or hanging down, and often with coppery colours and curved branches. 

Sphagnum auriculatum (denticulatum) is also present in VC55

Detailed photographs taken in the field and from a specimen.  We recommend that a detailed note of location or GPS reading is made and that a small specimen - e.g. two or three shoots - is retained in case this is needed for verification; all Sphagnum are rare or scarce in VC55 and should not be over-collected.

Fens, swamps, pools and ditches; often more base-rich than similar species

All year round.

Widespread and fairly frequent in Britain, but less common in parts of central and eastern England.
