Shrubs or trees, sometimes climbing shrubs, rarely herbs. Indumentum of simple, stellate, and/or other complex hairs. Leaves opposite or rarely whorled, without stipules, simple or 3-foliolate, less often palmately [or pinnately] compound. Inflorescences terminal or axillary, racemose, cymose, spicate, or thyrses. Flowers bisexual or polygamous by abortion, zygomorphic or rarely actinomorphic. Calyx persistent. Corolla 4- or 5- or more lobed; lobes usually spreading, aestivation overlapping. Fertile stamens inserted on corolla tube, alternate with lobes; filaments free; anthers dorsifixed, 1- or 2-locular, dehiscing by longitudinal slits or sometimes a circular pore. Ovary entire or 4-grooved, 2-8-locular; ovules 1 or 2 per locule, erect or pendulous. Style terminal, simple, entire or 2-cleft. Fruit a drupe or indehiscent capsule, sometimes breaking up into nutlets. Seeds (1 or) 2-4, endosperm usually absent, seed coat thin; embryo straight, as long as seed; radicle short, inferior.
Some 91 genera and ca. 2000 species: primarily tropical and subtropical, 20 genera and 182 species in China.
The classification of Verbenaceae is in a state of flux, especially regarding its relationship to Lamiaceae. There is evidence to suggest a significant division between members of subfamily Verbenoideae, genera 1-5 in this account, and the remaining genera, including genera 6-20, which for convenience are here referred to as subfamily Viticoideae s.l. The latter are more closely allied to each other and to genera traditionally kept within Lamiaceae (including genera 1-8 in this Flora) . Avicennia is often placed in a family of its own, but its affinities are clearly with Viticoideae, especially genera 17-19 in this account which have traditionally been placed in a separate subfamily, Symphorematoideae.[1]
Trees or shrubs. Branches glabrous or sparsely pubescent. Leaves opposite, palmately (1-) 3-8-foliolate; leaflets petiolulate, margin entire, dentate, serrate, or incised. Inflorescences terminal or axillary cymes, thyrses, or panicles; bracts usually small, often early deciduous. Calyx campanulate, tubular, or funnelform, sometimes 2-lipped, usually truncate or shortly 5-dentate. Corolla blue, white, or yellow, 2-lipped, lower lip 3-lobed with middle lobe greatly elongated, upper lip usually 2-lobed. Stamens 4, didynamous, sometimes exserted; anther locules attached only at tip, becoming divaricate. Ovary 2-4-locular; ovules 1 or 2 per locule. Style filiform; stigma 2-cleft. Drupes subtended by enlarged calyx, globose, ovoid, or obovoid, normally 4-locular and 4-seeded but often some locules suppressed and base of pyrene forming a hollowed cavity, endocarp a bony pyrene, mesocarp generally fleshy. Seeds obovoid or oblong, endosperm absent; cotyledons usually fleshy.
About 250 species: chiefly tropical, few in temperate regions of both hemispheres; 14 species in China.[2]
