Charles D. Bell

[Perennial herb], subshrub to tree; hairs often stellate or glandular. Leaf: generally opposite, simple or compound, generally toothed; stipules generally 0. Flower: generally bisexual; calyx teeth or lobes [2]5; corolla small, radial, rotate, lobes [3–4]5; stamens [4]5, epipetalous; ovary ± inferior, chambers 1 or 3–5, 1-ovuled; styles ± 0 or 3–5. Fruit: drupe.
5 genera, 200 species: especially northern temperate, also South America, southeastern Asia, tropical Africa. [Backlund & Bremer 1997 Plant Syst Evol 207:225–254] Incl in Caprifoliaceae in TJM (1993), and possibly in future. —Scientific Editors: Thomas J. Rosatti, Bruce G. Baldwin.
Unabridged note: Incl in Caprifoliaceae in TJM (1993), and possibly in future according to the Angiosperm Phylogeny Website (, 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."

Shrub, slender, generally hairy, also ± glandular, especially in inflorescence, generally deciduous. Leaf: simple, entire to lobed. Inflorescence: compound cyme, umbel-like, generally terminal, rounded or ± flat-topped, generally with oblanceolate bracts, marginal flowers larger, sterile or all flowers ± alike; peduncles 1.5–4 cm; rays generally 7. Flower: ovary chambers 1 (2 abort), ovule pendent; style short, stigma lobes 3. Fruit: drupe, drupe-like. Seed: 1.
± 250 species: northern temperate, subtropics. (Latin: for pliable branches used in binding) [Clement et al. 2014 Amer J Bot 101:1029–1049] Viburnum rigidum naturalized in San Francisco Bay Area (Tilden Park); material previously identified as Viburnum edule belongs instead to Viburnum opulus.
