Molecular and morphological evidence for hybrid origin and matroclinal inheritance of an endangered wild rose, Rosa × pseudobanksiae (Rosaceae) from China

The distinction between hybrids and species of hybrid origin is significant for plant diversity conservation. Interspecific hybridization within the genus Rosa is a common phenomenon. Based on field observation, we hypothesized that one previously published species, Rosa pseudobanksiae (endangered category: CR) might be a hybrid. In this study, we utilized molecular approaches involving three nuclear markers and four plastid markers to examine...
