Carex acutiformis - Lesser Pond-sedge
Very rare in Cornwall and found only in riverine marshes. Many of the old records are doubtful (Margetts & David, 1981), but the record made for ' Tregear Moor' in 1907 by C.C. Vigurs (Herb. N.H.M.) is correct. However, the place name is mis-spelt in both Davey (1909) and Margetts & David (1981). When Vigur's original specimen was examined it was found to be labelled ' Tregair Moor, Newlyn East' . Using this information the sedge was refound growing in a deep ditch by a field hedge, east of Trevemper Bridge not far from the present course of the Gannel (SW85J, 1998, I.J.Bennallick & H.M.Meredith). It continues to be frequent in the river marshes in the Gunwalloe and Poldhu valleys (SW62Q) but the recent record made for the Helford River (SW72D) is likely to be an error and is possibly C. riparia.
