Discussion | 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).

The name Ipomoea aristolochiifolia G. Don has been misapplied to plants of I. cardiophylla. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
