(1) A genus of plants(Convolvulus) of the family Convolvulaceae. The plants can be twining or nontwining herbs and shrubs. There are approximately 250 species, distributed mainly in the temperate regions. In the USSR there are 30 species. The most common is the lesser bindweed,(C. arvensis), a persistent perennial soboliferous weed with pale-rose slightly aromatic flowers. The plant grows on cultivated and fallow land, along dams, in ravines, and in other similar habitats. As green fodder bindweed is poisonous in large quantities, but it is harmless in hay. The desert species, C. divaricatus and C. erinaceus, are valuable feed plants. The species C. subhirsutus grows in the forest foothills of Middle Asia. A highly toxic plant of the Crimea, Asia Minor, and the Near East is C. scammonia.
