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.) |
After fires, Ipomoea tenuissima seeds germinate and seedlings thrive for about a year. The plants then disappear except in sites that remain open. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
