|discussion=<p><i>Phalaris arundinacea</i> is a circumboreal species, native to north-temperate regions; it occurs, as an introduction, in the Southern Hemisphere. It grows in wet areas such as the edges of lakes, ponds, ditches, and creeks, often forming dense stands; in some areas it is a problematic weed. North American populations may be a mix of native strains, European strains, and agronomic cultivars (Merigliano and Lesica 1998).</p><!--
--><p>The interpretation adopted here is that of Baldini (1995), who treated <i>Phalaris arundinacea</i> sensu stricto as the most widespread species in a complex of three species. The other two species are P. rotgesii (Husn.) Baldini, a diploid that is restricted to France and Italy, and P. caesia Nees, a hexaploid that grows in southern Europe, western Asia, and eastern to southern Africa. <i>Phalaris</i> rotgesii has glumes 2-3.8 mm long, sterile florets 1-1.5 mm long, bisexual florets 2-3 mm long, and anthers about 2 mm long. The corresponding measurements for P. caesia are 6-7 mm, about 2.5 mm, 4-5 mm, and 3.5-4 mm, respectively. Other taxonomists have included P. rotgesii and P. caesia in <i>P. arundinacea</i>. Only <i>P. arundinacea</i> sensu stricto has been found in North America.</p><!--
--><p>A sterile form of <i>Phalaris arundinacea</i> with striped leaves—<i>P. arundinacea</i> <i></i></i>var.<i><i> picta</i> L., also referred to as <i>P. arundinacea</i> forma variegata (Parn.) Druce—is known as 'Ribbon Grass' or 'Gardener's Gaiters', and is sometimes grown as an ornamental. Baldini (1995) noted that it sometimes appears to escape, and is never found far from a cultivated stand.</p><!--
--><p><i>Phalaris arundinacea</i> hybridizes with other species of <i>Phalaris</i>. One hybrid, P. xmonspeliensis Daveau [= <i>P. arundinacea</i> x <i>P. aquatica</i>] is grown for forage.</p>
