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.) |
Leaf shape in Ipomoea hederacea, and, perhaps, in other ipomoeas, is under simple genetic control and is useless for recognition of varieties (C. D. Elmore 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
