Valeriana acutiloba Rydb.
Downy-fruit Valerian, Sharpleaf Valerian
Valerianaceae (Valerian Family)
USDA Symbol: VAAC
Small, slightly bilaterally symmetrical, white flowers in branched clusters atop a stem with largest leaves at base.
The mostly undivided, basal leaves help distinguish this from other similar species, which have divided leaves. This species is variable, and by some botanists is divided into at least three species: Cordilleran Valerian (V. acutiloba), the most southwesterly, has hairless leaves and stems; Downy-fruit Valerian (V. pubicarpa), more westerly, has hairless leaves but hairy stems; California Valerian (V. californica), also westerly, has hairy leaves and stems. Valeriana comes from the Latin valere ("to be strong") and refers to the medicinal qualities of the plants. Extracts were used as a nerve tonic and are said, under certain circumstances, to relax better than opium. Valerian was one of 72 ingredients Mithridates, king of Pontus in the second century b.c., compounded as an antidote to poison, using poisoned slaves as test subjects.
