QUE SIGNIFIE STINGING HAIR EN ANGLAIS
Stinging plant
Une plante piqûre ou une plante aux cheveux piquant est une plante avec des poils sur ses feuilles ou tiges qui sont capables d'injecter des substances dans des animaux qui causent une douleur ou une irritation. D'autres plantes, telles que les opuntias, ont des cheveux ou des épines qui provoquent une irritation mécanique, mais ne pas injecter de produits chimiques. Les cheveux sévères se déroulent particulièrement chez les familles Urticaceae, Loasaceae, Boraginaceae et Euphorbiaceae. De tels cheveux ont été révélés pour dissuader les mammifères de pâturage, mais ne sont plus efficaces contre les attaques d'insectes que les poils non piquants. Beaucoup de plantes avec des poils piquants ont le mot «ortie» dans leur nom anglais, mais peuvent ne pas être liées à «véritables orties». Bien que plusieurs familles de plantes non apparentées aient des cheveux pessailleux, leur structure est généralement similaire. Une base solide supporte une seule cellule allongée à pointe cassante. Lorsque la pointe est cassée, le point pointu exposé pénètre dans la peau et la pression injecte des toxines. Les produits chimiques précis impliqués dans la douleur et l'irritation ne sont pas encore entièrement compris.
