Schoenoplectus tabernaemontani (C.C. Gmel.) Palla (Scirpus tabernaemontani C.C. Gmel., S. lacustris ssp. tabernaemontani (C.C. Gmel.) Syme, Schoenoplectus lacustris ssp. tabernaemontani (C.C. Gmel.) Á. & D. Löve) - Grey Club-rush.
Differs from S. lacustris in stems to 1.5m, glaucous, usually 3-8mm wide at mid-point; and glumes minutely (x20 lens) but densely papillose at least near midrib and apex; stigmas 2; nut 2-2.5mm, biconvex or plano-convex; 2n=42. Native; in similar places to S. lacustris but also in marshes, dune-slacks and wet peaty places, mostly near sea; frequent throughout most of British Isles, except very scattered inland. Despite its similarity to S. lacustris, molecular evidence suggests that the 2 sspp. are quite distinct and no hybrids have been recorded in British Isles.
