It is often assumed that selection by biotic agents drives floral variation, but abiotic factors are also known to influence floral traits. Understanding trait covariations and their association with diverse environmental factors is a central question in evolution and ecology. Here, we studied covariation in floral and vegetative traits in relation to climate and topo\u2010edaphic variation in the orchid\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Platanthera dilatata<\/jats:italic>\n                    <\/jats:styled-content>\n                    .

Phenotypes were distributed among geographic regions, as well as habitats. Plants with larger leaves, inflorescences, sepals, and lips tended to predominate in coastal meadows with moderate climates, while those with smaller traits tended to predominate in continental wet meadows with extreme climates, as well as fens and muskeg bogs. Nectar spur length was poorly correlated with leaf, inflorescence, and flower size and had lower correlations with climatic factors, suggesting that spurs respond to other factors. Differentiating among varieties by spur\u2013lip length relationships may be problematic because of continuous independent variation in both traits.
