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.) |
A report of Ipomoea hederifolia from Kansas was presumably based on a cultivated plant, and a report for Vermont (J. T. Atwood et al. 1973) was presumably based on waifs that did not persist. The report of I. hederifolia for New Mexico by W. C. Martin and C. R. Hutchins (1980) was based on misidentified specimens. Ipomoea hederifolia may be established in Virginia. The names Ipomoea coccinea and Quamoclit coccinea (Linnaeus) Moench have been misapplied to plants of I. hederifolia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
