Figure 3From: Evolution of a hotspot genus: geographic variation in speciation and extinction rates in Banksia(Proteaceae)Temporal patterns of Banksia diversification. (a) Accumulation of lineages through time for a sample of 250 Banksia phylogenies from the Bayesian posterior distribution. The solid line connects the median divergence times for each number of lineages. (b) Distribution of values of the gamma statistic for the 250 phylogenies.Back to article page
