Extended Data Figure 6: Geographic patterns of median ages for the Chinese angiosperm genera.

a–i, Median ages for all genera, woody genera and herbaceous genera (from left to right), based on all sampled genera (a–c), the youngest 25% of genera (d–f), and the oldest 25% of genera (g–i) in each grid cell. j–l, Null-model test to identify recent (blue grid cells) and ancient (red grid cells) divergence centres for all genera (j), woody genera (k) and herbaceous genera (l). The analyses include 2,592 angiosperm genera (woody genera, n = 925; herbaceous genera, n = 1,501; genera with both woody and herbaceous species, n = 166).
