FIGURE 1. The strict consensus tree obtained from the combined (rps4, trnL-F, atpB-rbcL, trnG and ITS) dataset. Numbers above branches indicate bootstrap values from Bayesian inference analysis (=0.5), maximum likelihood analysis (=50%) and maximum parsimony analysis (=50%).
FIGURE 2 in Iris tibetica, a new combination in I. ser. Lacteae (Iridaceae) from China: evidence from morphological and chloroplast DNA analyses
FIGURE 2. Median-joining network based on combined sequences of four cpDNA regions, depicting the relationships among haplotypes of 136 individuals from 59 localities across the geographic range of Iris ser. Lacteae. Each white circle represents a haplotype and the size of the circle is proportional to the number of individuals with that haplotype. Haplotype codes correspond to those in Table 1. Black dots indicate missing haplotypes (extinct or not sampled). Haplotypes of A, B, and C haplogroups are encircled with thin lines.

FIGURE 4. Phylogenetic analysis of Iris ser. Lacteae based on psbA–trnH/rps4–trnS/trnS–trnG/trnL–trnF sequences. Neighbour-joining tree is shown with bootstrap values in 1000 replicates for NJ/MP/ML analyses (shown only when> 50%) above the branches and Bayesian posterior probabilities more than PP = 0.90 below the branches. Clades I and II within I. ser. Lacteae are indicated. Haplotypes and locality codes are given in Table 1.

FIGURE 3 in Iris tibetica, a new combination in I. ser. Lacteae (Iridaceae) from China: evidence from morphological and chloroplast DNA analyses
FIGURE 3. Genetic clustering of Iris ser. Lacteae haplotypes from 136 individuals inferred with the program BAPS. Each vertical column corresponds to one haplotype, and black vertical lines separate haplotypes from the different localities. Locality codes are given in Table 1. Different colours represent the different genetic cluster (blue-cluster 1, red-cluster 2, green-cluster 3). (a) Mixture clustering results revealing three clusters with a posterior marginal probability of 0.80; (b) Bar plot from the admixture results. The vertical bars are split into several colours when there is evidence for the admixture (P <0.05). Localities are ordered according to latitude, from south to north.

Data from: Phylogeographical patterns of an alpine plant, Rhodiola dumulosa (Crassulaceae), inferred from chloroplast DNA sequences
The phylogeographical patterns of Rhodiola dumulosa, an alpine plant species restrictedly growing in the crevices of rock piles, were investigated based on 4 fragments of the chloroplast genome. To cover the full distribution of R. dumulosa in China, 19 populations from 3 major disjunct distribution areas (northern, central, and northwestern China) were sampled. A total of 5881bp (after alignment) of chloroplast DNA (cpDNA) from 100 individuals were sequenced. The combined cpDNA data set yielded 36 haplotypes. The total genetic diversity of R. dumulosa was remarkably high (H T = 0.981). The interpopulation genetic differentiation was significantly large (F ST = 0.8537, P < 0.001), possibly due to the long-term isolation of the natural populations. N ST was significantly larger than G ST (P < 0.001), indicating the presence of phylogeographical structure among the R. dumulosa populations. We propose 2 migration steps to explain the current distribution of R. dumulosa in China. First, this species migrated from refugia in the Qinghai-Tibetan Plateau to northern areas via the intervening highlands when temperatures increased; second, the highland populations migrated toward the mountaintops when temperatures increased further because R. dumulosa is adapted to cold environments. During the second migration step, the common ancestral haplotypes may have been gradually lost.
