Phytelephas, or the vegetable ivory palms, are dispersed across South America. The clade has a total of eight species, and Phytelephas branches off to have six species. The phylogenetic relationships are not completely understood, so it is unclear which species of the vegetable ivory palms that P. tenuicaulis is most closely related to.
