Ancestral State Reconstructions (ASR) for the sub-clades of <i>Saxifraga</i> sect. <i>Trachyphyllum</i>.

<p>Only members of sect. <i>Trachyphyllum</i> Clade T2 are shown (not <i>S. aspera</i> or <i>S. bryoides</i> because they were not included in the morphological analyses given their divergent phylogenetic positions). Sub-clades used in the ASR analyses are numbered (from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0069814#pone-0069814-g005" target="_blank">Fig. 5</a>). The first three columns denote the focal clades depicted in the subsequent bar plots (note that the bottom row is for sub-clade 1 = <i>Trachyphyllum</i>), geographic location (white = North America, gray = Beringia, black = Eurasia), and subsection classification (white = <i>Criomorphicae</i>, gray = <i>Dentaphyllae</i>, black = <i>Xeromorphicae</i>), respectively. These columns are followed by the morphological characters and traits inferred for each sub-clade through the ASR analyses in SIMMAP. Only significant ASR's are shown; the absence of a bar indicates no significant trait was inferred. White and gray shading denote traits within each character as labeled.
