Plants having petals that are fused or joined together; a botanical classification of flowering plants with united petals.
From Greek 'gamos' (fusion/union) + Latin 'petala' (petals). Classical Linnaean botanical classification, largely replaced by modern phylogenetic systems.
Linnaeus divided flowers into those with separate petals and those with fused petals—it was a simple system, but it reveals how some flowers evolved to be more protective and efficient.
