Caprifoliaceae A.L. de Jussieu.
Circumscription of the family is controversial. Various segregate families (or reassignments) of taxa traditionally placed in the Caprifoliaceae have been proposed, including the transfer of Sambucus and Viburnum to the Adoxaceae, placement of Diervilla and Weigela in the Diervillaceae (Backlund & Pyck 1998), placement of Abelia and Linnaea in the Linnaeaceae (Backlund & Pyck 1998; Pyck et al. 2002), and retention of Lonicera, Symphoricarpos, and Triosteum in a much more narrowly circumscribed Caprifoliaceae. Alternatively, all these taxa could be included in the Caprifoliaceae, along with Dipsacaceae and Valerianaceae, as a more broadly circumscribed Caprifoliaceae (APG III 2009). Kadereit & Bittrich (2016) adopt an intermediate solution.
