ORDER 53. VALERIANaCEae. (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.

1. VALERIaNA, 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 dicious or dimorphous. (A mediaeval Latin name of uncertain origin.)

Fruit 3-celled, two of the cells empty and sometimes confluent into one, the other 1-seeded.--Annuals and biennials, usually smooth, with forking stems, tender and rather succulent leaves (entire or cut-lobed towards the base), and white or whitish cymose-cl.u.s.tered and bracted small flowers.--Our species all have the limb of the calyx obsolete, and are so much alike in aspect, flowers, etc., that good characters are only to be taken from the fruit. They all have a rather short corolla, the limb of which is nearly regular. (Name a diminutive of Valeriana.)

[*] _Corolla bluish; fruit with a corky ma.s.s at the back of the fertile cell._

V. OLITRIA, Poll. Fruit flattish, obliquely rhomboidal; empty cells as large as the fertile, contiguous, the thin part.i.tion at length breaking up.--Old fields, N. Y. to Penn. and La. (Nat. from Eu.)
