135 * VALERIANACEAE 
Herbs or shrubs, annual or sometimes perennial; often woody at the base; branching often dichotomous. Leaves exstipulate, opposite or in a basal rosette, bases usually sheathing or connate, entire or pinnafid to pinnately divided. Inflorescence cymose, terminal. Flowers often numerous, actinomorphic or zygomorphic, bisexual; receptacle epigynous. Calyx often poorly developed. Sepals 1–25, united at the base into a short tube, small at anthesis, enlarging in the developing fruit, often plumose, persistent. Petals 5, united into a basal tube, a conspicuous nectariferous spur sometimes present. Stamens 1–4, alternating with the petals; filaments adnate to the corolla tube; anthers bilocular, dehiscing by longitudinal slits. Ovary inferior, 3-locular but only one locule fertile and with a single ovule; style slender; stigma finely 2- or 3-lobed, rarely entire. Fruit a cypsela.
A widespread family of 17 genera and 315 species, occurring chiefly in the Northern Hemisphere but extending to South America, South Africa, and Indonesia; 3 genera naturalized in Australia; in Tasmania 2 genera naturalized. The family is placed in the Dipsacales near Dispsacaceae (Eurasia, Africa) and Morinaceae (Balkans to China).
The Tasmanian representatives of the family are weeds of cultivation; however, the family contains some species of minor pharmaceutical and culinary value. The leaves of some species of Valerianella (Corn-salads) are occasionally used as a salad green (chiefly in Europe), and extracts of the herb Valeriana officinalis L. (Valerian) are popular as natural remedies for insomnia and nervous anxiety.
