Fig. 1: Remarkable diversification rate heterogeneity across Cactaceae.
From: Identifying the multiple drivers of cactus diversification

Branches are coloured by speciation rates estimated with BAMM28 and vary 32-fold. Arc segments of median speciation rate for thirteen morphologically varied cactus genera are indicated.
