Fig. 1. Strict consensus tree of 128 most‐parsimonious trees of 772 steps derived from equally weighted maximum parsimony analysis of sequences of the ITS region of Bupleurum and outgroup (OG) taxa (CI = 0·58; RI = 0·85). Bootstrap percentages appear above the branches (boldface); jackknife percentages are given in brackets; values <50 % are not indicated. Decay indices are below the branches in italics. Clade A = subgenus Penninervia; clade B = subgenus Bupleurum; clade C = the ‘NW African’ group; clade D = ‘Macaronesian’ group; clade E = the ‘Iberian and Balearic’ group; clade F = the ‘Ranunculoides’ group; clade G = the ‘Trachycarpa’ group; clade I = the ‘Perfoliata’ group.
