Within and nested clade distances are given, in miles, for both interior (I) and tip (T) clades. PSS, P-value for a significantly small value; PSL, P-value for a significantly large value. I-T distance is the interior clade distance minus the tip clade distance. Inferences based on Templeton key are given for each clade.
