Dipentodon, Gerrardina, Petenaea, Tapiscia and Allies

Huerteales is an order of flowering plants. It is one of the 17 orders that make up the large eudicot group known as the rosids in the APG III system of plant classification. Within the rosids, it is one of the orders in Malvidae, a group formerly known as eurosids II and now known informally as the malvids. This is true whether Malvidae is circumscribed broadly to include eight orders as in APG III, or more narrowly to include only four orders.

Huerteales consists of four small families, Petenaeaceae, Gerrardinaceae, Tapisciaceae, and Dipentodontaceae. Out of its constituent families, Heurteales also consists of six genera. Petenaeaceae consists of a single genus and species Petenaea cordata from southern Mexico, Guatemala and Belize. Gerrardinaceae consists of a single genus, Gerrardina. Tapisciaceae has two genera Tapiscia and Huertea. Dipentodontaceae was treated as consisting of a single genus, Dipentodon until the genus Perrottetia was added to Dipentodontaceae in the late 2000s. The largest genus, Perrottetia, contains about 15 of the approximate total of 25 species in the order.
