(A) Estimated speciation rates in Velloziaceae lineages and (B, C) estimated logarithm of the number of species (logN.spp) accumulation through time (in millions of years) for selected lineages of Velloziaceae. All Velloziaceae: includes all five genera of the family; core-Barbacenia + core-Vellozia: the infra-generic clades within these genera exhibiting the highest probability for having suffered shifts in their diversification rates relative to the background rates simulated by BAMM analyses (delimitated by nodes 157 and 209, respectively).
