ORDER 68. LOGANIaCEae. (LOGANIA FAMILY.)
_Herbs, shrubs, or trees, with opposite and entire leaves, and stipules or a stipular membrane or line between them, and with regular 4--5-merous 4--5-androus perfect flowers, the ovary free from the calyx_; a connecting group between Gentianaceae, Apocynaceae, Scrophulariaceae (from all which they are known by their stipules) and Rubiaceae, from which they differ in their free ovary; our representatives of the family are all most related to the Rubiaceae, to which, indeed, they have been appended.

Capsule elliptical, flattened contrary to the narrow part.i.tion, 2-celled, septicidally 2-valved. Seeds many or several, winged. Embryo straight, in fleshy alb.u.men; the ovate flat cotyledons much shorter than the slender radicle.--Smooth and twining shrubby plants with ovate or lanceolate leaves, minute deciduous stipules, and showy yellow flowers, of two sorts as to relative length of stamens and style. (_Gelsomino_, the Italian name of the Jessamine.)
1. G. sempervirens, Ait. (YELLOW JESSAMINE of the South.) Stem climbing high; leaves short-petioled, s.h.i.+ning, nearly persistent; flowers in short axillary cl.u.s.ters; pedicels scaly-bracted; flowers very fragrant (the bright yellow corolla 1--1' long); capsule flat, pointed.--Low grounds, E.

Capsule short, 2-celled, twin, laterally flattened, separating at maturity from a persistent base into 2 carpels, which open loculicidally, few-seeded.--Chiefly herbs, with opposite leaves united by stipules, and the flowers spiked in one-sided cymes. (Named for _Adrian Spiegel_, latinized _Spigelius_, who wrote on botany early in the 17th century, and was perhaps the first to give directions for preparing an herbarium.)
