Abstract
ON the basis of the chromosome count of 2n= 126±2 (ref. 1), Spartina townsendii H. & J. Groves was generally considered to be 2n= 126 until 1963, when Marchant (ref. 2) first recorded 2n=120, 122 and 124 for plants in Britain. Seed-producing S. townsendii at Baldoyle near Dublin has also been found to have 2n= 124 (ref. 3). A preliminary account of this grass was given in 1961 (ref. 4). The account is correct in general essence (ref. 3) but the chromosome number was incorrectly stated to be 2n=126 and a photograph used in illustration was misinterpreted as showing three quadrivalents and fifty-seven bivalents. In fact, the photograph shows one trivalent, one univalent and either two quadrivalents and fifty-six bivalents or sixty bivalents.
