Figure 4
Distribution of bootstrap support values for phylogenetic position of three clades in genus  Pinus . a) Bootstrap support values for placement of subsection Krempfianae . Circles correspond to placement of P. krempfii sister to subsection Gerardianae . b) Bootstrap support values for placement of Pinus merkusii / P. latteri . Circles correspond to placement of P. merkusii/P. latteri as sister to subsection Pinaster and triangles as sister to subsection Pinus. c) Bootstrap support values for placement of subsection Contortae. Circles correspond to placement of subsection Contortae as sister to subsection Australes and triangles as basal to both subsections Australes and Contortae. For all charts, filled data points correspond to An partition sizes falling between final decrease of branch score metric values and start of decrease in overall bootstrap support values for An partitions, as shown in Figure 3. Squares represent variable phylogenetic placements not including those represented by circles or triangles. Arrows in b) and c) indicate partition size at which bootstrap support for monophyly of clade falls below 100%.
