FIG. 2 in Phylogeny and biogeography of wild roses with specific attention to polyploids

FIG. 2. Phylogenetic relationships among Rosa species as reconstructed by Maximum Likelihood analyses of three chloroplast regions (psbA-trnH spacer, trnL region and trnG region). Bootstrap values are placed as close as possible to the node supported. The ploidy level of each species is given after its name (see Erlanson, 1929, 1934, 1938; Roberts, 1977; Yokoya et al., 2000; Roberts et al., 2009; Jian et al., 2010). The names of known polyploids are in bold (in R. sect. Caninae all species are presumed to be polyploids even when the ploidy number is not exactly known). Wissemann's (2003) classification is compared with our clades. A P designates our Pimpinellifoliae clade, a C our Cinnamomeae clade, an S our Synstylae clade, Ca our Caninae clade and Ru our Rubiginae clade.
