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.) |
