Le Myosotis des champs (Myosotis arvensis<\/em>) est une plante herbac\u00e9e hermaphrodite annuelle (\u00e0 bisannuelle) de la famille des Boraginac\u00e9es (Boraginaceae).
\nLe genre comprend 50 esp\u00e8ces dans les r\u00e9gions temp\u00e9r\u00e9es. De nombreuses vari\u00e9t\u00e9s sont utilis\u00e9es dans les jardins.
\nTige dress\u00e9e, raide, ramifi\u00e9e \u00e0 la base et peu feuill\u00e9e, enroul\u00e9e en crosse \u00e0 son extr\u00e9mit\u00e9 portant 2 \u00e0 3 inflorescences. L\u2019inflorescence\u00a0en cyme biscorpio\u00efde, raide, nue, s\u2019allongeant beaucoup pendant la floraison.
\nFeuilles alternes, les inf\u00e9rieures subsessiles, en rosette l\u00e2che, \u00e0 limbe elliptique, plus large dans la partie sup\u00e9rieure\u00a0; les caulinaires sessiles, \u00e0 limbe lanc\u00e9ol\u00e9, plus ou moins aigu au sommet.
\nPetites fleurs roses, puis bleues, \u00e0 corolle rotac\u00e9e, de 3 \u00e0 5 mm de large, \u00e0 5 lobes concaves. A maturit\u00e9, le calice, \u00e0 tube h\u00e9riss\u00e9 de poils \u00e9tal\u00e9s, crochus au sommet,\u00a0 devient conique et se referme, le p\u00e9doncule s’allonge et se redresse. Cela sert \u00e0 caract\u00e9riser le myosotis des champs, des nombreuses esp\u00e8ces de ce genre.
\nInfrutescence\u00a0\u00e0 4 ak\u00e8nes brun noir\u00e2tre fonc\u00e9\u00a0; p\u00e9dicelle fructif\u00e8re \u00e9cart\u00e9, \u00e9tal\u00e9, 1 \u00e0 3 fois plus long que le calice.
\nLes poils du Myosotis des champs sont non piquants\u00a0; ce caract\u00e8re est une exception chez les borraginac\u00e9es.
\nC’est une esp\u00e8ce commune dans les champs, les chemins et les lieux incultes.
\nLe Myosotis des champs n’est pas une plante tr\u00e8s utilis\u00e9e en phytoth\u00e9rapie. Pourtant, elle est efficace pour lutter contre les bronchites chroniques. C’est \u00e9galement un anti-inflammatoire, un s\u00e9datif et un tonique. On utilise les feuilles et les sommit\u00e9s fleuries.<\/p>\n","protected":false},"excerpt":{"rendered":"
