Primary concordance trees inferred at the α of 100 (a) and 0.1 (b) using BUCKy.

<p>The α parameter represents the <i>a priori</i> level of discordance expected among loci, where a high α assumes a high level of discordance among the gene trees and a low α assumes a low level of discordance. 246 loci with at least two parsimony informative sites covering eight <i>Diapensia</i> samples were used in the BUCKy analyses. Sample IDs refer to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0140175#pone.0140175.t001" target="_blank">Table 1</a>. The concordance factors (CFs) and their 95% confidence intervals are shown on the branches; those in bold did not overlap with any conflicting CF, and those in bold and with an asterisk had no conflicting splits.
