Annual, perennial herb, occasionally strongly scented, odor generally unpleasant. Leaf: simple to pinnately lobed or compound; petioles generally sheathing; basal ± whorled; cauline opposite, petioled to sessile. Inflorescence: cyme, panicle, or head-like, generally ± dense. Flower: generally bisexual; calyx fused to ovary tip, limb 0 or lobes generally 5–15, coiled inward, plumose in age, pappus-like, spreading in fruit; corolla radial to 2-lipped, lobes generally 5, throat generally > lobes, > tube, base generally spurred or swollen, tube slender, long or short; stamens generally 1–3, fused to petals; ovary inferior, chamber generally 1, or occasionally 3 but 2 empty or vestigial. Fruit: achene, smooth, ribbed, or winged.
± 17 genera, 300 species: generally temperate, worldwide except Australia. Some species cultivated (Centranthus), some medicinal (Valeriana). [Bell & Donoghue 2005 Organisms Diversity Evol 5:147–159] —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
Key to Valerianaceae
[Annual] perennial herb from rhizome or short underground caudex, glabrous to soft-hairy. Stem: generally erect, 1–several. Leaf: basal simple to pinnately lobed or compound, tapered to petiole; cauline ± sessile to ± clasping, pinnately lobed to compound, distal lobe generally > others. Inflorescence: cyme, clustered, ± dense to open, terminal or axillary. Flower: calyx lobes 5–15, rolled inward, plumose in age, spreading, persistent in fruit; corolla ± funnel-shaped, white to pink, lobes ± equal, throat >> tube, occasionally swollen near base, tube slender, occasionally obscured by swollen throat; stamens 3; ovary ± 1-chambered. Fruit: generally compressed, generally 6-veined vertically.Key to Valeriana
± 200 species: temperate worldwide except Australia. (Latin: strength, from use in folk medicine, or after Valerian, a Roman emperor) [Bell & Donoghue 2005 Organisms Diversity Evol 5:147–159]
Plants glabrous or sparsely hairy. Stem: 1–7 dm; nodes short-hairy. Leaf: 3–30 cm; at least some basal leaves lobed to compound; cauline deeply lobed to compound, lobes or leaflets generally 3–7, lanceolate to round. Flower: generally bisexual; corolla 5–8 mm, white or ± pink, throat ± 2 × lobe length. Fruit: 4–6 mm, lanceolate to ± oblong. [Online Interchange]
