&lt;br /&gt;
Las salviniáceas (o helechos flotantes) son helechos acuáticos con dos representantes bien definidos: Salvinia es un conocido invasor de diques y aguas estancadas, Azolla es cultivado en los campos de arroz debido a su asociación con una bacteria fijadora de nitrógeno. Los dos géneros están agrupados en la misma familia porque comparten su estructura de reproducción antes llamada &amp;quot;esporocarpo de origen indusial&amp;quot;, hoy considerada soro sostenido por un soróforo con (en Azolla) o sin (en Salvinia) cubierta del soróforo (ver referencias). También, a diferencia de otros helechos acuáticos, son los únicos helechos flotantes, no arraigados a ningún sustrato.&lt;br /&gt;
&lt;br /&gt;
== Ciclo de vida ==&lt;br /&gt;
Las salviniáceas son plantas vasculares con ciclo de vida haplodiplonte donde la alternancia de generaciones es bien manifiesta, con esporofito y gametofito multicelulares e independientes, con esporas como unidad de dispersión y de resistencia. El gametofito es un &amp;quot;talo&amp;quot; (cuerpo sin organización), y el esporofito es un &amp;quot;cormo&amp;quot; (con raíz, vástago y sistema vascular). Debido a estas características tradicionalmente se las agrupa con las &amp;quot;pteridofitas&amp;quot;.&lt;br /&gt;

M! : meiosis,&lt;br /&gt;

&lt;br /&gt;
== Caracteres ==&lt;br /&gt;
Poseen esporofitos con megafilos o &amp;quot;frondes&amp;quot; (Euphyllophyta).&lt;br /&gt;
Raíces presentes (Azolla) o ausentes (Salvinia). Tallos protostélicos, ramificados dicotómicamente.&lt;br /&gt;
Hojas sésiles (sin pecíolo), dispuestas en el tallo de forma alterna, pequeñas (entre 1 y 25 milímetros de longitud), redondeadas a oblongas, enteras. Venas libres (Azolla) o anastomosadas (Salvinia).&lt;br /&gt;
&lt;br /&gt;
Esporas de dos morfos (plantas heterospóricas): megasporas grandes y microsporas pequeñas. Esporas globosas, trilete. Germinación endospórica.&lt;br /&gt;
&lt;br /&gt;
Número de cromosomas x = 9 (Salvinia, el menor número de cromosomas encontrado en helechos), 22 (Azolla).&lt;br /&gt;
&lt;br /&gt;
Reinterpretación del esporocarpo. A la vista de que salviniáceas y marsileáceas poseen un ancestro común, y que el &amp;quot;esporocarpo de origen indusial&amp;quot; de las salviniáceas no es homólogo al &amp;quot;esporocarpo de origen foliar&amp;quot; de las marsileáceas, Nagalingum, Schneider y Pryer proponen que el &amp;quot;esporocarpo de origen indusial&amp;quot; de las salviniáceas pase a llamarse directamente soro, que la rama portadora de soros pase a llamarse esporoforo (homólogo al esporoforo de marsileáceas) y se considere que las salviniáceas poseen un esporocarpo que ha perdido la cubierta del esporocarpo en forma secundaria (Nagalingum, Schneider y Pryer 2006[1] ).&lt;br /&gt;
&lt;br /&gt;
== Ecología y Evolución ==&lt;br /&gt;
Plantas acuáticas flotantes, no arraigadas.&lt;br /&gt;
Subcosmopolitas.&lt;br /&gt;
El registro fósil comienza en el Cretácico (Collinson 1996[2] ).&lt;br /&gt;
Taxonomía&lt;br /&gt;
Taxones superiores: Plantae (clado), Viridiplantae, Streptophyta, Streptophytina, Embryophyta, Tracheophyta, Euphyllophyta, Monilophyta, Clase Polypodiopsida, Orden Salviniales, familia Salviniaceae. Incluye Azollaceae.&lt;br /&gt;
