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]
