Table 1 Phylogenetic signal of presence/absence of chemical traits using the D-metric.

Compounds	D	P (D = 1)	P (D = 0)
Imidazole Alkaloids
P = probability that D-metric is equal to 0 or 1. If P is greater than 0.05 then it is not significantly different from that value of D. When D = 1 there is no phylogenetic signal, and there is a random distribution. When D = 0 there is phylogenetic signal and the trait follows Brownian motion. Bolded values represent significant p-values. * indicates compounds that cannot be analyzed since present in all.
