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.) |
Ipomoea triloba seeds are sometimes a contaminant in rice and other seeds. Ipomoea trifida (Kunth) G. Don (Convolvulus trifidus Kunth) was incorrectly ascribed to Florida by J. K. Small (1933) on the basis of an unusual and incorrectly identified specimen of I. triloba. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
