a stick or staff with notches that was "offered to the idols" (see Molina); a type of cactus (see Karttunen); or, twisted (see Mikulska), such as a twisted foot or leg (sometimes referring to someone with a limp)
The Florentine Codex, Book 11, folio 141v-142r, includes a plant called xonecuilpatli (which would also be spelled xonecuilpahtli with the glottal stop). This plant is the source of a remedy for gout in the form of a beverage. It can also be rubbed onto the body. The plant can sting like a scorpion bite. One who is paralyzed can be cured by taking a bath in the infusion. Incidentally, the image of the plant suggests nothing twisted or bent, so the origin of the name is unclear.
xonecuilli = "palabra que se aplicaba en general a la forma torcida (Contel, comunicación personal, 2012)" (p. 101)
xonecuilli = "tortilas en forme de S." (Wimmer 2004)
