Calliergon giganteum Giant Spear-moss

A pleurocarpous moss of wet base-rich swamps and marshes, fens, flushes and boggy places near streams and rivers. Less common than Calliergon cordifolium and may have declined in redcent years due to loss of habitat. It is rather scarce in West Glamorgan where it has been recorded in Crymlyn Fen and the Gors Llwyn.
