The family Loganiaceae includes about 13 genera and 420 species. Its limits have changed substantially since the account in the Flora of Somlia was prepared. Only one of the four genera included there, Strychnos, is still included in the family. The description above attempts to reflect the characteristics of the family as now interpreted. As a practical point, Strychnos, has globose to subglobose fleshy berries.
