Figure 3From: Hybrid floral scent novelty drives pollinator shift in sexually deceptive orchidsFloral scent profiles. Floral scent differentiation among taxa in the Ophrys hybrid zone investigated. Canonical discriminant function (CDF) plot of all odour compounds (relative proportions, in %) found in epicuticular extracts of the Ophyrs flowers. Functions 1 and 2 account for 100% (86.0% and 14.0%, respectively) of the total variability in floral odour among orchid taxa.Back to article page
