The Dipsacales are an order of flowering plants, included within the asterid group of dicotyledons.
Under the Cronquist system, the order included Adoxaceae, Caprifoliaceae, Dipsacaceae, and Valerianaceae.
Under the more recent Angiosperm Phylogeny Group (APG II) system, the circumscription of the order is much the same but the families are circumscribed differently.
APG includes Adoxaceae and a broadly circumscribed Caprifoliaceae, the latter including the alternatively acceptable families Diervillaceae, Dipsacaceae, Linnaeaceae, Morinaceae, and Valerianaceae.
Under the APG II definition some well-known members of Dipsacales are honeysuckle, elder, viburnum, and valerian.
A few other families may also belong near this order. These include the Columelliaceae, Paracryphiaceae, and Sphenostemonaceae.
Dipsacales 350 species
Caprifoliaceae (honeysuckle family) 800 species
Adoxaceae 150-200 species
