Isolepis setacea Bristle Club-rush

A common annual or short-lived perennial sedge of wet acidic sites, often along sandy or gravelly tracks or on the dges of ponds and lakes and sometimes growing with Isolepis cernua in dune slacks and other wet habitats. It is ditributed throughout Britain in suitable habitats and it is found widely in West Glamorgan and possibly under recorded. It differs from Slender Club-rush (Isolepis cernua) in its bracts which overtop the blackish spikelets at the top of the stem and the balck, shiny seeds that have distinct ridges (best viewed with a stereo, dissecting microscope or a good hand lens).
