Arbre caducifoli\u00e9, dio\u00efque, atteignant 20 m de haut, \u00e0 port tr\u00e8s irr\u00e9gulier. Tronc plus ou moins droit et lisse, parfois tr\u00e8s tortueux, pouvant exceptionnellement atteindre jusqu\u2019\u00e0 1 m de diam\u00e8tre. \u00c9corce gris\u00e2tre-blanch\u00e2tre.

Feuilles alternes, glauques, concolores, glabres, longuement p\u00e9tiol\u00e9es, tr\u00e8s polymorphes. Chez les arbres jeunes sont fr\u00e9quentes les feuilles lanc\u00e9ol\u00e9es, enti\u00e8res, parfois pourvues d\u2019une dent dans la moiti\u00e9 sup\u00e9rieure.

Fleurs des chatons femelles \u00e0 p\u00e9dicelle beaucoup plus long (8-12 mm), disque semblable \u00e0 celui des fleurs m\u00e2les et ovaire termin\u00e9 en 3 grands stigmates pourpr\u00e9s. Fruit en capsule ovo\u00efde-allong\u00e9e, lisse, coriace, d\u00e9hiscente en 2-3 valves, qui renferme de nombreuses graines \u00e0 poils blanch\u00e2tres.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-12200","species","type-species","status-publish","hentry"],"acf":[],"yoast_head":"\nPopulus euphratica Oliv. - North Africa Trees<\/title>\n<meta name=\"robots\" content=\"noindex, follow\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Populus euphratica Oliv. - North Africa Trees\" \/>\n<meta property=\"og:description\" content=\"Arbre caducifoli\u00e9, dio\u00efque, atteignant 20 m de haut, \u00e0 port tr\u00e8s irr\u00e9gulier.
