Table S1. Evolutionary transitions among nontolerators, tolerators, and endemics for 23 California genera with exhaustively sampled molecular phylogenies.

Table S2. Bayes factor tests of successive rate restrictions for 23 California genera.

Table S3. GenBank accession numbers for previously published taxa ("i" = ITS, "e" = ETS; "t" = trnL, "r" = rp116, "n" = ndhF), serpentine affinity ("nt" = nontolerator; "t" = tolerator; "e" = endemic), and geographic proximity to serpentine ("y" = exposed, "n" = not exposed) for taxa in our sample.

Figure S1. The states and allowed transitions in BiSSE (a) and GeoSSE (b).

Figure S2. Comparison of endemic richness per genus in the California flora and the endemic richness per genus in our sample.

Figure S3. Consensus trees for each of the 23 genera, where character states are labeled by serpentine affinity (black = endemic, grey = tolerator, white = nonendemic), and nodes are labeled with the associated posterior probability.

Figure S4. Ages (horizontal axis; substitutions per site) of congeneric nonendemics (number of taxa as bars) and endemics (open circles on x-axis).

Figure S5. Differences in diversification rate (speciation rate -- extinction rate) along branches inferred to be in the serpentine endemic state with the diversification rate of branches inferred to be in the nonendemic state.
