Le Regnellidium diphyllum<\/em><\/strong> (commun\u00e9ment appel\u00e9 regnellidium \u00e0 deux feuilles<\/strong> ou tr\u00e8fle d’eau \u00e0 deux lobes<\/strong>) est une foug\u00e8re aquatique ou semi-aquatique<\/strong> rare appartenant \u00e0 la famille des Marsileacea<\/span><\/mark>. C’est l’unique esp\u00e8ce vivante (genre monotypique) de son genre. Originaire du sud du Br\u00e9sil<\/strong> et des r\u00e9gions adjacentes de l’Argentine<\/strong>, elle se distingue par ses feuilles uniques qui ressemblent \u00e0 des tr\u00e8fles \u00e0 deux feuilles ou \u00e0 des papillons.<\/div>\n
<\/div>\n
<\/div>\n
    \n
  • Feuillage bilob\u00e9 :<\/strong> Contrairement au genre voisin Marsilea<\/em> qui poss\u00e8de quatre folioles (fa\u00e7on tr\u00e8fle \u00e0 quatre feuilles), le Regnellidium<\/em> n’en poss\u00e8de que deux<\/strong> en forme d’\u00e9ventail.<\/span>\u00a0<\/li>\n
  • Aspect papillon :<\/strong> Ses deux lobes de 8 \u00e0 10 cm flottent ou \u00e9mergent de l’eau, lui donnant l’allure d’un papillon vert brillant.<\/span><\/li>\n
  • Croissance :<\/strong> Elle se propage gr\u00e2ce \u00e0 des rhizomes rampants<\/strong> et des stolons qui s’enracinent dans le sol. Sa hauteur varie g\u00e9n\u00e9ralement entre 8 et 20 cm<\/strong>.<\/span>\u00a0<\/li>\n
  • Reproduction :<\/strong> Comme toutes les foug\u00e8res, elle ne fleurit pas mais produit des spores enferm\u00e9s dans des structures sph\u00e9riques appel\u00e9es sporocarpes<\/strong>, situ\u00e9es \u00e0 la base de ses tiges.<\/span><\/li>\n

    \u00a0Habitat et conditions de culture<\/div>\n
      \n
    • Profondeur id\u00e9ale :<\/strong> Elle s’\u00e9panouit pleinement plant\u00e9e sous 10 \u00e0 30 cm d’eau , ce qui en fait une excellente plante de berge pour les bassins d’ornement.<\/span>\u00a0<\/li>\n
    • Substrat :<\/strong> Elle pr\u00e9f\u00e8re un sol riche et argileux<\/strong>.<\/span>\u00a0<\/li>\n
    • Aquariophilie :<\/strong> Bien qu’elle soit parfois test\u00e9e en aquarium, son acclimatation y est compliqu\u00e9e et elle s’adapte beaucoup mieux \u00e0 la vie en bassin ext\u00e9rieur ou en paludarium.<\/span>\u00a0<\/li>\n
    • Rusticit\u00e9 :<\/strong> Elle tol\u00e8re bien le froid \u00e0 condition que ses stolons restent immerg\u00e9s sous le niveau du gel en hiver.<\/span>\u00a0<\/li>\n

      \u00a0Statut de conservation<\/div>\n
      L’esp\u00e8ce est consid\u00e9r\u00e9e comme vuln\u00e9rable<\/strong> dans son milieu d’origine. Ses populations naturelles en Am\u00e9rique du Sud font face \u00e0 la d\u00e9gradation de leurs habitats (zones humides et mares) en raison de la pollution, notamment par les rejets de cuivre qui nuisent gravement \u00e0 son d\u00e9veloppement.<\/div>\n","protected":false},"excerpt":{"rendered":"
