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.) |
Varieties 3 (2 in the flora). Variety australis (O’Donnell) D. F. Austin is known from Argentina. Varieties cordatotriloba and torreyana appear to differ by minor, trivial traits; nevertheless, they have distinctive aspects and, historically, distinct ranges and habitats. Both have been dispersed by humans and may appear sporadically in places outside their historical ranges. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
