The Distribution of Halogeton Sativus (L.) C. A. Meyer in Morocco

Abstract

In the search for natural enemies of Halogeton glomeratus (Bieb.) C. A. Meyer, a noxious weed introduced into the United States, studies were made, in 1959-61, on the distribution of H. sativus, a closely related species, occurring within Morocco. This plant is found in the Rif Mountains in the north, throughout the Moulouya River Valley, along the Ziz River Valley, scattered along the southern slopes of the High Atlas Mountains as far west as Amerzgane, with an apparently discontinuous area of distribution on the northern slopes of the High Atlas in the vicinity of Asni.
