The families Viscaceae and Eremolepidaceae are included in the family Santalaceae by the APG. The genera Dipentodon (Dipentodontaceae) and Medusandra (family Medusandraceae) are regarded as unplaced by APG II (as is the family Balanophoraceae, now likely to be reincluded; see above).
The family Medusandraceae consisted of two genera: Soyauxia and Medusandra. Molecular evidence place the former within the family Peridiscaceae of the order Saxifragales, and the latter within the order Malpighiales close to Passifloraceae-Turneraceae-Malesherbiaceae. The chinese monotypic genus Dipentodon is close to Tapiscia and is proposed to constitute the new order Huerteales with Tapisciaceae and the genus Perrottetia formerly placed in the family Celastraceae.
