Ever since "Dipentodon" was named in 1911, there had been occasional suggestions that it might be related to "Tapiscia" and "Huertea". In 2001, Alexander Doweld established the order Huerteales, defining it to consist of "Tapiscia", "Huertea", and "Dipentodon". This grouping was later supported by molecular phylogenetic studies. In 2006, a study of DNA sequences showed that "Perrottetia" was misplaced in Celastrales and that it is sister to "Dipentodon" in Huerteales. Also in 2006, it was found that "Gerrardina" is a malvid, but its placement within this group remained uncertain.
