A family of tropical shrubs and trees known for their colorful flower clusters, commonly called coral plants.
From Latin 'corallium' (coral) plus the taxonomic suffix '-idae' used to denote families in biological classification. The name refers to the coral-like appearance of the flowers. This naming convention was standardized in the 18th and 19th centuries as scientific taxonomy developed.
The '-idae' suffix is the international standard for naming animal families in taxonomy, but here it's applied to plants because of their striking resemblance to coral—a perfect example of how scientists use visual metaphors to organize the natural world.
