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.

In the flora area, Ipomoea indica rarely produces seeds and rarely survives winters. It is probably native in southern Florida.
