Comments:  Ipomoea batatas is a early introduction throughout the Pacific. The above lists documented locations, but it is undoubtedly present on many more islands.

Introduced and naturalized in undisturbed habitats in the Galápagos Islands.

Additional information:
Additional online information about Ipomoea batatas is available from the Hawaiian Ecosystems at Risk project (HEAR).

Information about Ipomoea batatas as a weed (worldwide references) may be available from the Global Compendium of Weeds (GCW).

Taxonomic information about Ipomoea batatas may be available from the Germplasm Resources Information Network (GRIN).
