Abstract

<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:RelyOnVML/> <o:AllowPNG/> </o:OfficeDocumentSettings> </xml><![endif]--><p class="MsoNormal" style="line-height: 200%; tab-stops: 163.05pt;"><em style="mso-bidi-font-style: normal;"><span style="mso-ansi-language: ES-MX;">Alternanthera philoxeroides</span></em><span style="mso-ansi-language: ES-MX;"> (Mart.) Griseb. es una maleza introducida en algunas partes del mundo, y a menudo se comporta como planta invasora severa en cuerpos acuáticos. Se reporta aquí por primera vez en México. El material botánico se recolectó en los márgenes del río Bravo, dentro del municipio de Matamoros, Tamaulipas. Además de la descripción botánica e ilustración detallada de la especie, se anexa una clave de identificación para las especies de <em style="mso-bidi-font-style: normal;">Alternanthera</em> registradas en Tamaulipas. La especie es relevante para la conservación de la flora nativa de México, por lo que se recomienda la erradicación de las poblaciones descritas y tomar medidas que eviten su diseminación en otros humedales del país.</span></p><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves/> <w:TrackFormatting/> <w:HyphenationZone>21</w:HyphenationZone>
