Fig. 1.

The single shortest tree from successive weighting of plastid rbcL and matK (analysis A) for Ruscaceae s.l. and related groups of Asparagales. Numbers of substitutions are indicated below each branch (DELTRAN optimization), and bootstrap percentages >50 % are given above each branch. Triangles indicate branches not present in the strict consensus tree of 5760 equally MP trees by Fitch analysis (equal weight). Tree length is 5435 steps with CI = 0·70 and RI = 0·85. The dashed line in the lower left-hand corner marks the point where the non-core asparagoids are attached to this part of the tree (non-core taxa are not shown; this part of the tree is identical to that show in Fig. 2).
