Cactus Flashcards

Q

Une aréole coussinée, avec ou sans épines, est un signe certain d’un véritable cactus.

A

Les cactus ont des aréoles. Ce sont de petites excroissances duveteuses à partir desquelles poussent les épines, les nouvelles ramifications et les fleurs. Elles peuvent être blanches, beiges ou jaunes, mais sont présentes sur tous les cactus. Aucune autre famille de plantes n’a des aréoles. Donc, si vous regardez de près une plante succulente qui ressemble à un cactus et ne voyez aucune aréole, comme c’est le cas avec les euphorbes, cette plante n’est certainement pas un cactus! La présence ou l’absence d’aréoles est de loin la façon la plus simple de distinguer les deux.
