Discussion

The report of Ipomoea capillacea from Alabama (J. T. Kartesz and C. A. Meacham 1999) was probably based on a specimen of I. muricata.

In the flora area, Ipomoea purpurea may be native in southeastern United States and introduced elsewhere. Populations in California, Oregon, and Washington may not be truly naturalized.
