Abstract: The scientific names of twentythree alien vascular plants in North America, originating from East Asia, are reviewed here, since their uses in North America are different from those in East Asia. Most are taken from the invasive plants literatures in North America as well as in Europe, but a few are also from native floras in East Asia. The synonyms for each accepted species, along with their distributions both in North America and in East Asia, with discussion if necessary, are also provided.

Key words: Invasive Plants
