46. R. maritimus L. , Sp.Pl. 335 (1753) .

Annual 10-50(-70) cm; plant golden-yellow when fruit is ripe. Basal leaves narrowly elliptical, tapering nearly equally at both ends. Branches of panicle arcuate; all whorls except the lower ones confluent when ripe. Pedicels very slender, somewhat longer than the valves. Valves 2-5-3 x 1-5-2 mm (excluding teeth), ovate-triangular, with a narrow, triangular apex; teeth usually 2 on each side, setiform, longer than the width of the valve. Nut 1*3—1*5(—1-8) mm. 2« = 40. Sea-shores and other wet places. Most o f Europe except the south and the extreme north. Au Be Br Cz D a Fe G a Ge Hb He H o?Hs H u It Ju N o Po Rm Rs (B, C, W, K, E) Su. In localities where both R. palustris and R. maritimus are found it is not always easy to decide which was involved in forming a particular hybrid, except for the evidence provided by the larger valves of R. palustris , with relatively shorter teeth. Hybrids in which either of these species takes part tend to have long branches, remote whorls, all subtended by leaves, and strongly toothed valves. The most frequent of such hybrids is R. crispus x palustris .
