Discussion
Collections of Polypremum procumbens were gathered from ship ballast piles in New Jersey (in 1865, 1875) and Pennsylvania (in 1865, 1868), and there was an 1873 report from Long Island, New York.
Since a report from Hawaii (F. R. Fosberg 1962), populations of Polypremum procumbens have been discovered in widely scattered locations, often near roads or runways, in the Pacific Basin. Specimens have been examined from the Territory of Guam, Kwajalein Atoll of the Republic of Marshall Islands, the Republic of Palau, Wallis Island, and one site in eastern Australia.
