Comments: For a recent taxonomic revision of this and other Caribbean Pilosocereus, see Franck et al. (2019). For a current review of P. robinii, see the U.S. Fish and Wildlife Species Profile. See also our Natives For Your Neighborhood website and Florida Natural Areas Inventory's Field Guide to the Rare Plants of Florida page (Chafin 2000).For a digitized image of Elbert Little's Florida range map, visit the Exploring Florida website. So records of this in South Florida may refer to P. millspaughii.
