The Dipsacales are an
order of
flowering plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed with ...
s, included within the
asterid group of
dicotyledon
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, ...
s. In the
APG III system of 2009, the order includes only two families,
Adoxaceae
Adoxaceae, commonly known as moschatel family, is a small family of flowering plants in the order Dipsacales, now consisting of five genera and about 150–200 species. They are characterised by opposite toothed leaves, small five- or, more rar ...
and a broadly defined
Caprifoliaceae
The Caprifoliaceae or honeysuckle family is a clade of dicotyledonous flowering plants consisting of about 860 species in 33 to 42 genera, with a nearly cosmopolitan distribution. Centres of diversity are found in eastern North America and easte ...

Under the Cronquist system
The Cronquist system is a list of systems of plant taxonomy, taxonomic classification system of angiosperms, flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of ...
, the order included Adoxaceae, Caprifoliaceae sensu stricto, Dipsacaceae, and Valerianaceae. Under the 2003 APG II system, the circumscription of the order was much the same but the system allowed either a broadly circumscribed Caprifoliaceae including the families Diervillaceae, Dipsacaceae, Linnaeaceae, Morinaceae, and Valerianaceae, or these families being kept separate. The APG III system only uses the broadly circumscribed Caprifoliceae.[
The Dipsacales appear to be most closely related to the Paracryphiales.][
