Sagittaria rigida
(
Anglèis
)
fornì da wikipedia EN
Sagittaria rigida, the sessilefruit arrowhead[2] or Canadian arrowhead,[3] is an aquatic plant species native to Canada and to the United States and also naturalized in Great Britain. It grows in shallow waters along the edges of ponds and streams. What is really interesting is that it has narrow oval leaves rather than the iconic arrowhead shaped leaves of species like the Sagittaria latifolia. it has sessile female flowers, which is where it gets its name from. Its flowers are very similar to other plants in the Sagittaria family, with three white petals. It grows "potato" like tubers which can be eaten. Gathering any tubers from the Sagittaria family can be dangerous if gathered from polluted water.[4][5]

Sagittaria rigida
Sagittaria rigida, communément appelé la Sagittaire dressée, Sagittaire rigide[3] ou encore la pointe de sessilefruit ou Canadian Arrowhead[4], est une espèce de plantes aquatiques originaire du Canada et des États-Unis et également naturalisée en Grande-Bretagne. Il pousse dans les eaux peu profondes le long des bords des étangs et des ruisseaux. Il a généralement des feuilles linéaires à étroitement elliptiques et des fleurs femelles sessiles.
Description
Sagittaria rigida est une plante herbacée vivace à rhizomes fins, de taille moyenne (80 cm, croissant plutôt en colonies. Se reconnait à la forme de ses feuilles, généralement dépourvues des lobes caractéristique des sagittaires, et à la courbure en « S » de sa hampe qui ramène ses fleurs au ras de la surface de l'eau.
Tige réduite au collet, prolongée par une hampe triangulaire dans le haut. Formes des rhizomes (ou stolons) blancs et spongieux (environ 45 x 0,5 cm), produisant à leur extrémité une nouvelle rosette de feuilles ou un petit tubercule blanc, arrondi (1 x 1,2 cm), terminé par une griffe charnue (2,5 cm).
Utilisation
Alimentaire
Ses tubercules, enveloppées d'une fine pelure brunâtre (non violacée), s'apprêtent comme ceux de la sagittaires à larges feuilles.
