Loganiaceae

 

a family of dicotyledonous plants. They are trees and shrubs; some are lianas or herbs. The leaves are opposite, simple, and entire. The flowers are bisexual and generally regular; the calyx and the corolla are usually five- or three-parted. The gynoecium consists of two or, rarely, three carpels; the ovary is usually superior but sometimes half-inferior. The fruit is a capsule or berry; rarely is it a drupe.

There are approximately 20 genera (more than 450 species), distributed in the tropical and subtropical regions of both hemispheres. No wild species are found in the USSR or Western Europe. Many species are poisonous and contain alkaloids; the nux vomica tree (Strychnos nux vomica) is of medical importance. Some Loganiaceae are ornamental. To the Loganiaceae are often assigned only six genera (about 100 species); the remaining genera are classified in other families, including Strychnaceae and Potaliaceae.
