Petenaeaceae consists of a single genus and species Petenaea cordata from Southern Mexico, Guatemala and Belize.[6]
Gerrardinaceae consists of a single genus, Gerrardina.[7] Tapisciaceae has two genera, Tapiscia and Huertea.[8][9]
Until 2006, Dipentodontaceae was treated as consisting of a single genus, Dipentodon.[10] Since that time, some authors have included Perrottetia in Dipentodontaceae, even though no formal revision of the family has been published as of 2008.[11] Thus the order Huerteales consists of six genera. The largest genus, Perrottetia, contains about 15 of the approximate total of 25 species in the order.[12]

History
Until the first decade of the twenty-first century, the five genera of Huerteales had usually been placed into three unrelated families. Tapiscia and Huertea had long been known to be related. Most authors had placed them in
For most of the twentieth century, Gerrardina and Dipentodon had usually been placed in Flacourtiaceae, a family that is now recognized by only a few taxonomists, and then only as a segregate of Salicaceae.[16][17] Perrottetia, meanwhile, had usually been placed, with considerable doubt, in Celastraceae.[18]
Ever since Dipentodon was named in 1911, there had been occasional suggestions that it might be related to Tapiscia and Huertea.
In 2009, Andreas Worberg and co-authors produced the first phylogenetic study that included all of the genera of Huerteales. From one of their data matrices, they derived a well supported phylogeny for the order, as well as strongly supported relationships among the four orders of malvids.[5]
