Discussion | Ipomoea imperati was collected once in Pennsylvania (on ballast in 1865). The names I. littoralis (Linnaeus) Boissier 1875, not Blume 1826, and I. stolonifera (Cirillo) J. F. Gmelin are illegitimate; both have been misapplied to plants of I. imperati. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ipomoea muricata has been spread as a contaminant in soybean seeds (C. R. Gunn 1970). The name Ipomoea turbinata Lagasca is illegitimate and has been misapplied to plants of I. muricata (G. W. Staples et al. 2006). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
