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 shumardiana is known only from areas where I. leptophylla and I. pandurata are sympatric; the names I. longifolia and I. pandurata have been misapplied to plants of I. shumardiana. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
