Representative specimen · Loganiaceae

Key pattern

Opposite, simple leaves joined at the base by a small connecting stipule on trees, shrubs, and climbers; regular, five-lobed tubular flowers store bitter alkaloids and ripen into a capsule or berry.

Several genera (Strychnos) are the source of some of the most potent plant alkaloids known, including strychnine — used historically both as a poison and, in minute doses, as a stimulant.
