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.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

In the southeastern United States, Ipomoea ×leucantha results from crosses between I. cordatotriloba and I. lacunosa that may be effected by honeybees (Apis mellifera); elsewhere, I. × leucantha is presumably introduced.
