Genera In Family: 4 genera, 35 species: especially northern temperate. Note: Incl in Caprifoliaceae in TJM (1993), and possibly in future.
Unabridged Note: Incl in Caprifoliaceae in TJM (1993), and possibly in future according to the Angiosperm Phylogeny Website (http://www.mobot.org/MOBOT/Research/APweb/welcome.html), which states, in part, "The whole lot might usefully be combined in a Caprifoliaceae s.l. (see also APG 2003), since similarities between the families are considerable and differences are mostly slight."
