  1. Phylogenetic signal (D-statistic) on a randomly selected subset of 1,000 Bayesian trees within the 95% credible set of uses of Euphorbia31 classified into level 1 state categories according to the Economic Botany Data Collection Standard (EBDCS). Out of all level 1 state categories only medicines shows phylogenetic signal (in bold). N: Number of species.
  2. a* 95% p < 0.05; *** all p < 0.005.
  3. bweak: <90% p(D > 0) > 0.05; moderate: 90% p(D > 0) > 0.05; strong: 95% p(D > 0) > 0.05; very strong: all p(D > 0) > 0.05.
