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.

Ipomoea wrightii may be spread as a contaminant in seeds.

The names Ipomoea heptaphylla (Roxburg) Voigt and I. pulchella Roth have been misapplied to plants of I. wrightii.
