The evolutionary relationships between species and average values of explanatory plant traits (solid circles) and flammability traits (open circles). Trait values are indicated by the size of the circles. A non-zero phylogenetic signal was found for leaf SA/V ratio (Pagel's λ = 1; P = 1 for λ = 1; P < 0.001 for λ = 0), leaf flaming time (Pagel's λ = 0.45; P = 1.0 for λ = 1; P < 0.001 for λ = 0) and leaf combustion rate (Pagel's λ = 0.99; P = 0.93 for λ = 1; P = 0.037 for λ = 0).
