Calyx-lobes lanceolate, persistent. Corolla funnel-form, the limb 4–5-lobed. Stamens 4–5. Style filiform, 2-cleft, stigmas capitate. Fruit dry, twin, of 2 indehiscent 1-seeded carpels.—A slender procumbent herb, with square stems, lanceolate pungent leaves in whorls of 4–6, and small subsessile blue or pinkish flowers surrounded by a gamophyllous involucre.

Order 53. VALERIANÀCEÆ. (Valerian Family.)
Herbs, with opposite leaves and no stipules; the calyx-tube coherent with the ovary, which has one fertile 1-ovuled cell and two abortive or empty ones; the stamens distinct, 1–3, fewer than the lobes of the corolla, and inserted on its tube.—Corolla tubular or funnel-form, often irregular, mostly 5-lobed, the lobes imbricated in the bud. Style slender; stigmas 1–3. Fruit indehiscent, 1-celled (the two empty cells of the ovary disappearing), or 3-celled, two of them empty, the other 1-seeded. Seed suspended, anatropous, with a large embryo and no albumen.—Flowers in panicled or clustered cymes. (Roots often odorous and antispasmodic.)
1. VALERIÀNA, Tourn. Valerian.
Limb of the calyx of several plumose bristles (like a pappus) which are rolled up inward in flower, but unroll and spread as the seed-like 1-celled fruit matures. Corolla commonly gibbous near the base, the 5-lobed limb nearly regular. Stamens 3.—Perennial herbs, with thickened strong-scented roots, and simple or pinnate leaves. Flowers in many species imperfectly diœcious or dimorphous. (A mediæval Latin name of uncertain origin.)
[*] Root spindle-shaped, large and deep (6–12´ long); leaves thickish.
1. V. édulis, Nutt. Smooth, or minutely downy when very young; stem straight (1–4° high), few-leaved; leaves commonly minutely and densely ciliate, those of the root spatulate and lanceolate, of the stem pinnately parted into 3–7 long and narrow divisions; flowers in a long and narrow interrupted panicle, nearly diœcious; corolla whitish, obconical (2´´ long).—Wet plains and prairies, Ohio and Ont. to Iowa, Minn., and westward. June.
