Caprifoliaceae A. L. Jussieu

忍冬科

Description from Flora of China

Shrubs or woody climbers, rarely small trees or herbs. Leaves opposite, rarely whorled, simple or pinnatifid, conduplicate or involute in vernation; interpetiolar stipules absent or rarely well developed. Inflorescence thyrsoid, axillary or terminal, compact or lax, cymes 1-, 2-, or 3-flowered; paired flowers sometimes with ovaries ± fused. Cymes with a pair of bracts and 2 pairs of bracteoles, located at base of ovaries, ± fused, occasionally accrescent in fruit, rarely absent. Flowers bisexual, actinomorphic or zygomorphic. Calyx 4- or 5-lobed. Corolla epigynous, gamopetalous; lobes 4 or 5, spreading, sometimes bilabiate, aestivation imbricate. Stamens (4 or)5, didynamous, alternating with corolla lobes, sometimes exserted; anthers free, 2-celled, opening by longitudinal slits, introrse. Ovary inferior, carpels 2-8, fused; placenta axile; ovules 1 to many per locule, some of which can be abortive, pendulous; style solitary; stigmas capitate or lobed. Fruit a berry, a drupe with 2-5 pyrenes, or a leathery achene. Seeds 1 to many; embryo small, straight; endosperm copious.

Following recent phylogenetic studies (Bell et al., Harvard Pap. Bot. 6(2): 481-499. 2001; Donoghue et al., Harvard Pap. Bot. 6(2): 459-479. 2001; W. H. Zhang et al., Molec. Phylogen. Evol. 26: 176-189. 2002), Caprifoliaceae is now thought to include Caprifolieae, Diervilleae, Linnaeeae, Morinaceae, Dipsacaceae, and Valerianaceae. However, Blacklund and Pyck (Taxon 47: 657-661. 1998) preferred to retain Caprifolieae as a distinct family and raise Linnaeeae and Diervilleae as new families, and this system is followed in the Flora of China.

Five genera and ca. 207 species: mostly in temperate regions of E Asia and E North America; five genera (one endemic) and 66 species (25 endemic) in China.
