Question: What does Cistus and Abelia have in common?
Sentence (from "Abelia"): Some authors, including the Angiosperm Phylogeny Group, consider "Abelia" and related genera to belong instead in the segregate family Linnaeaceae, also including such genera as "Linnaea", "Abelia", "Dipelta", "Kolkwitzia", and "Zabelia", but not such others as "Lonicera" or "Symphoricarpos," included by them instead in a more narrowly viewed Caprifoliaceae.
