Following resolution of the tree for the initial 14 species treated by Xu et al., the position of Oreolalax multipunctatus relative to the other spe- cies was estimated. Results Our PTP test showed the data set of Xu et al. has pat- tern which is significantly different from random. A PTP value of p< was obtained based on 999 ran- domized data sets. The minimum length tree derived from the randomized data was 64 steps whereas the minimum length tree from the original data was 58 steps. We interpret this pattern to reflect the presence of phylogenetic structure. Ten MPTs of 58 steps were found, each with a consistency index (CI; Kluge and Farris 1969) of CI = , and a retention index (RI; Farris 1989) of RI = When the data are mapped onto the tree of Xu et their tree was observed to have a length of 61 steps (CI = ; RI = ). Using PAUP, we found no. Figure 3. Three MPTs resulting from successive approximations weighting.

A strict consensus tree, Adams consensus tree (Adams 1972), and 50% majority consensus tree were generated from the ten MPTs respectively. The strict consensus tree (Fig. 2a) showed low resolving power. Only seven of 13 nodes were resolved demonstrating much conflict among various patterns of relationships. The Adams cons
