Ipomoea muricata
Ipomoea tenuiloba
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 two varieties of Ipomoea tenuiloba are comparatively easy to distinguish; there are intergrades (G. Yatskievych and C. T. Mason 1984), some approaching I. plummerae.
