Abstract

During a survey of weeds in the Novonikol' Ussuriisk district, Primorye territory, 13 new species were identified which had previously been cited neither in the Soviet flora nor in local literature source. Among the new weeds identified were several members of the Cassia, Amaranthus and Malva genera, Acanthospermum hispidum, Grindelia squarrosa and Anoda cristata. Most species had been introduced into the Soviet Union from the USA, Mexico and Argentina in soyabean imports destined for animal feed.
