Ancestral area optimization by S-DIVA and DEC model in the tribe Annoneae. Pie charts at nodes represent relative frequencies of ancestral area reconstructions using S-DIVA (left) and DEC (right) optimizations; single pie chart is shown for congruent S-DIVA and DEC results. Colours in the pie charts correspond with geographical areas (see inset map) except where superimposed with letters indicating broader ancestral areas; only two areas with the highest frequency are shown, while black is used to represent aggregated minor explanations. Numbers beside pie charts represent node numbers. Geological epoch abbreviations: PL = Pliocene; P = Pleistocene. Inset: Biogeographical areas used in the S-DIVA optimization. A: North America; B: South America; C: Africa excluding Madagascar; D: Southern India and Sri Lanka; E: continental Asia including southern China, Indochina, Thailand, Myanmar and north-eastern India; F: western Malesia; and G: Southeast Asia and Australasia, east of Wallace’s line
