报道西藏自治区林芝市发现的2种中国新外来植物：多籽藜Chenopodium polyspermum L.和瑞典藜C. suecicum Murr。两种植物在林芝市区绿化带和空地生长旺盛，并正常结实，说明其在西藏具有较强的入侵能力。调查表明，两物种可能通过进口草坪种子夹杂带入中国。
Two Chenopodium species alien to China, C. polyspermum L.and C. suecicum Murr, were discovered for the first time in Nyingchi, Tibet. These two species occupied the greenbelt and uncultivated land in Nyingchi, and could reproduce normally, indicating their invasive potential in Tibet. Our investigations indicated that they might be introduced accidentally with seeds of turf grass from United States of America.
