A new alien species of duckweed for Ukraine—lesser duckweed (<i>Lemna aequinoctialis</i> Welw.)—was discovered, to which this study is devoted. All other samples belonged to <i>Lemna minor</i>. The article presents the most complete description of the distribution of <i>L. aequinoctialis</i> Welw. in Europe, and also contains updated data on the species distribution of duckweeds in Ukraine. Six species of the genus <i>Lemna</i> are now known in Ukraine—three native and three alien. The ecological requirements of <i>L. aequinoctialis</i> are similar to those of <i>L. minor</i>.
