Discussion

Reports of Ipomoea nil from California are based on misidentified material of I. hederacea.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Ipomoea muricata has been spread as a contaminant in soybean seeds (C. R. Gunn 1970).

The name Ipomoea turbinata Lagasca is illegitimate and has been misapplied to plants of I. muricata (G. W. Staples et al. 2006).
