Discussion		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.
