Varieties 2 (2 in the flora).

Allionia incarnata was used by indigenous peoples to treat swellings, was added to baths to reduce fever, and also prepared as a decoction to treat diarrhea and kidney ailments (S. Cheatham et al. 1995, vol. 1). Occasionally fruits of A. incarnata are shallowly convex and resemble, in this respect, the fruits of A. choisyi.
