Dipsacales

Dipsacales, teasel or honeysuckle order of flowering plants, containing 46 genera and about 1,090 species, which are distributed worldwide but centred mainly in the Northern Hemisphere. The order is best known for its ornamental plants, such as honeysuckle (Lonicera), arrowwood and guelder rose (Viburnum), and scabious, or pincushion flower (Scabiosa).

Typically, plants in Dipsacales have opposite, often gland-toothed leaves, flowers in cymose (flat-topped) clusters, petals fused into a corolla tube (either regular or bilaterally symmetrical), and inferior ovaries. In most genera, petals are alike in shape, but some members of the order develop two-lipped flowers in which one half of the flower is the mirror image of the other half (bilateral symmetry). Most members of the order are shrubby, but there are a few herbaceous members as well.

The order has two families, Adoxaceae and Caprifoliaceae, and belongs to the asterid clade (organisms with a single common ancestor), or sympetalous lineage of flowering plants, in the campanulids group of the Angiosperm Phylogeny Group IV (APG IV) botanical classification system (see angiosperm).
