Fig 4. Result from 100 000 stochastic character-mapping reconstructions of life history (annual vs. perennial) on the MCC tree of the subtribe Panicineae using Phytools.

The colour of edges in the tree gives the posterior probability (computed as the relative frequency across stochastic maps) of each habit type through the branch of the clade. Red indicates high posterior probability of perennial habit. Pie charts on the main nodes of the Panicineae show character-state probability (blue, annual; red, perennial) from reconstructions in BayesTraits using the 1000 subsampled posterior trees and the rjMCMC method.
