Landoltia punctata (G. Mey.) Les & D.J. Crawford

Lesser Greater Duckweed; Dotted Duckweed; Dotted Duckmeat

Herb

Annual

Vascular

A native to eastern <strong>Australia</strong>, southeastern <strong>Asia</strong> and throughout the <strong>islands of the western Pacific</strong> (Ward 2011-see citation below).

This species has long been recognized as <em><strong>Spirodela punctata</strong></em> (Meyer) Thompson or <em><strong>Spirodela oligorrhiza</strong></em> (Kurz) Hegelm. <strong>Les and Crawford</strong> (1999) demonstrated that it should be recognized in a new monotypic genus from <em><strong>Spirodela</strong></em> and created the combination <em><strong>Landoltia punctata</strong></em> (G. Mey.) Les &amp; D.J. Crawford. <strong>Ward</strong> (2011) argued that the typification of <em><strong>Lemna punctata</strong></em> G. Mey (the basionym of <em><strong>S. punctata</strong></em>) was ambiguous and should be rejected along with the new genus <em><strong>Landoltia</strong></em> and combination <em><strong>L. punctata</strong></em>. Ward contended with the rejection of <em><strong>Lemna punctata</strong></em>, <em><strong>S. oligorrhiza</strong></em> was the correct name to be used. Thus far, most treatments have disagreed and have used <em><strong>Landoltia punctata</strong></em>.--<em>B.R. Keener</em>
