Ventenata dubia is a species of grass known by the common names North Africa grass and wiregrass. It is native to southern Europe, North Africa and the Middle East. It is becoming well known in North America, where it is an introduced species and a noxious weed of cultivated and disturbed habitat. It is problematic in the Pacific Northwest, where it was first identified in Washington in 1952[1] and Idaho in 1957.[2] It was found in Utah in 1996.[3] It probably spreads when it gets mixed in with grass seed and is transported and inadvertently planted.[3]
This is an annual grass growing 15 to 70 centimeters tall with thin, branching stems that are naked and wiry. These wiry stems make the grass hard to cut.[2][3] The inflorescence is an open panicle with very slender, spreading branches bearing spikelets at their tips. The spikelet is 1 to 1.5 centimeters in length and has riblike longitudinal veins. The upper flower has a wavy awn up to 1.5 centimeters long.

Ventenata dubia (la ventenatée, ou ventenate, douteuse) est une espèce de plantes monocotylédones herbacée de la famille des Poaceae, sous-famille des Pooideae, endémique du sud de l’Europe, du nord de l'Afrique et du Moyen-Orient.
Elle est connue en Amérique du Nord en tant qu'espèce envahissante, problématique dans le Nord-Ouest Pacifique où elle a été identifiée pour la première fois dans l'État de Washington en 1952[1], dans l'Idaho en 1957[2] et dans l'Utah en 1996[3]. La plante se dissémine probablement lorsque ses graines sont replantées car elles ont été mélangées aux semences de gazon[3].
C'est une plante herbacée annuelle aux tiges ramifiées qui croit jusqu'à une hauteur de 15 à 70 centimètres. Les tiges filiformes rendent cette herbe difficile à couper[2],[3]. Elle présente des inflorescences en panicules de 10 à 12 cm de long. Les axes secondaires de l'inflorescence regroupent des épillets de 1 à 1,5 centimètre de long.
