Charles D. Bell, family description

Subshrub [to small tree].
Leaf: opposite, simple [ compound]; stipules generally 0.
Flower: calyx tube fused to ovary, limb generally 5-lobed; corolla radial [or bilateral], rotate to cylindric, generally 5-lobed; stamens generally 4 inserted at 2 levels, epipetalous, alternate corolla lobes; ovary inferior, 1–5-chambered, style 1.
Fruit: achene or capsule, 1-seeded.
4 genera, 35 species: especially n temperate. [Donoghue et al. 2001 Harvard Pap Bot 6:459–479] Incl in Caprifoliaceae in TJM (1993), and possibly in future. —Scientific Editor: Thomas J. Rosatti.
Unabridged references: [Backlund & Pyck 1998 Taxon 47:657–661; Donoghue et al. 2001 Harvard Pap Bot 6:459–479]
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."
