Drepanocladus aduncus Kneiff's Hook-moss

A dioicous, pleurocarpous moss of very wet palaces in the lowlands such as ditches, fens, marshes and shallow pools. It is a variable hook moss which is sparingly branched and long-leaved when growing as floating masses in aquatic situations and upright and well branched with shorter and more hooked leaves when growing in marshy places. It is widely distributed in the southern half of Britain but rather local and mostly coastal in Wales. It is locally abundant in West Glamorgan, sometimes forming large, untidy sheets in marshy habitats in coastal sites including open mosaic habitats. Sporophyte capsules are rare.
