Hypothesized network of relationships in Sorbus based on the results compiled by Rich et al. (2010) including diploids and the intermediate polyploid taxa. Proposed genome compositions are also included with the relative DNA content and ploidy inferred using FCM. Dotted lines indicate either multiple or dubious origins. *Ploidy based on published chromosome numbers (Warburg and Kárpáti, 1968; Bailey et al., 2008).
