Molecular and morphological evidence for natural hybridization between PRIMULA secundiflora franchet and P. poissonii franchet (primulaceae)
Natural hybridization occurs commonly in plants and blurs their interspecific delimitation. It is unclear whether spontaneous hybridization occurs in natural populations of Primula in China. In this study we examined natural hybridization between P. secundiflora and P. poissonii based on morphological and molecular analyses of individuals with intermediate morphology.
