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 wrightii may be spread as a contaminant in seeds. The names Ipomoea heptaphylla (Roxburg) Voigt and I. pulchella Roth have been misapplied to plants of I. wrightii. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
