Relating to or belonging to the Cornaceae family (dogwoods); having characteristics typical of dogwood plants.
From Cornaceae (the dogwood family) plus the Latin adjectival suffix -ous, literally 'of or pertaining to Cornaceae.' Botanical classification adjective.
The cornaceous trait of producing bracts (colorful leaf-like structures) instead of showy petals is why dogwood flowers can look completely different from other trees—they're basically cheating at the pollinator attraction game.
