Callitrichales

Callitrichales is a proposed order of flowering plants. As circumscribed by American botanist Arthur Cronquist in the Cronquist system (1981), the order included three families: A feature is the single stamen in the flower.
 * Hippuridaceae
 * Callitrichaceae
 * Hydrostachyaceae

The order is not recognized by the Angiosperm Phylogeny Group; the family Hydrostachyaceae is placed in the order Cornales and the plants making up the other two families are included in the family Plantaginaceae.
