Common Name: VALERIAN Habit: [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. Etymology: (Latin: strength, from use in folk medicine, or after Valerian, a Roman emperor) Reference: Bell & Donoghue 2005 Organisms Diversity Evol 5:147--159

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
