Strychninea

Strychninea is a tribal grouping within the larger family of plants known as the Apocynaceae, which are commonly called dogbane or oleander. This tribe is characterized by specific botanical features that distinguish it from other groups within the Apocynaceae. Members of the Strychninea tribe are often woody plants, including trees and shrubs, though some may be herbaceous.

The reproductive structures, particularly the flowers, are key to identifying species within this tribe. They typically exhibit actinomorphic (radially symmetrical) symmetry and often have five petals. The fruits can vary, but many are berries or drupes. A significant genus within Strychninea is Strychnos, which famously includes species that contain the potent alkaloid strychnine. However, not all plants in the Strychninea tribe produce strychnine; the presence and type of alkaloids can vary greatly among species.

Geographically, the Strychninea tribe is found across tropical and subtropical regions worldwide. Their ecological roles are diverse, contributing to forest ecosystems and providing habitats or food sources for various animals. Research into the Strychninea tribe continues to explore their chemical compounds, evolutionary relationships, and potential medicinal properties, building upon the historical and ongoing interest in the genus Strychnos.
