並列摘要


The genus Ludwigia comprises about 80 species. It is one of the largest genera of the family Onagraceae. Six species and one natural hybrid of Ludwigia have been recorded from Taiwan. In our recent plant inventory surveys, three species were found to be new records from Taiwan. They are Ludwigia palustris (L.) Elliott in the northern region, Ludwigia decurrens Walt. in the northern and central regions, and Ludwigia erecta (L.) Hara in the central region of the island. This paper describes these species of Ludwigia with photos and distribution, and provides a key to all ten naturally occurring species of Ludwigia in Taiwan for identification.
