Discussion

In the flora area, Ipomoea indica rarely produces seeds and rarely survives winters. It is probably native in southern Florida.

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

Species 600+ (47, including 1 hybrid, in the flora).

Reports by J. T. Kartesz and C. A. Meacham (1999) of Ipomoea cordifolia Carey ex Voight from Alabama and I. meyeri (Sprengel) G. Don from Georgia have not been verified. Ipomoea horsfalliae Hooker is cultivated in Florida; it is not known to be established or recurrent in the flora area.

In protologue, Ipomoea gilana K. Keith & J. A. McDonald was reported to be similar to I. lindheimeri and to nest phylogenetically near I. orizabensis (G. Pelletan) Ledebour ex Steudel, which, in the broad sense, is known from Chihuahua, Mexico, and southward. Ipomoea gilana is known from the Black Range in southwestern New Mexico and will key here to I. indica.
