Fla., Tex., Mexico, West Indies, Central America, n South America, introduced Pacific Islands (Hawaii).
Discussion
The Florida populations have been called Acanthocereus floridanus but now appear to be the northernmost variants of the highly variable species A. tetragonus, which occurs throughout the Caribbean region (D. R. Hunt 1991).
The common name “triangle cactus” refers to the mature stems in cross section; the epithet “tetragonus” alludes to the juvenile stems, which often have four angles.
Selected References
None.
