The order of Dipsacales contains around 1,000 species of herbaceous and woody plants. Various species are used as ornamentals like the honeysuckles (Lonicera) or Scabiosa flowers. However, several species are invasive and have become important weeds like some honeysuckle species (e.g. Amur honeysuckle and Japanese honeysuckle). The flowers often have petals fused into a corolla tube.
The family Dipsacaceae is treated here as a subgroup (Dipsaceae) of the Caprifoliaceae
The group currently includes the following weed families:
