Differences in vegetative characteristics among 4 populations of senecio vulgaris possibly due to interspecific hybridization


, : Differences in vegetative characteristics among 4 populations of senecio vulgaris possibly due to interspecific hybridization. Annals of Botany (London) 40(165): 125-128

Leaf vegetative characteristics of S. vulgaris plants were examined for evidence of introgression by S. squalidus. S. vulgaris plants are more similar to S. squalidus in an area of high S. squalidus frequency than elsewhere, but the expected greater similarity of the radiate form of S. vulgaris to S. squalidus is seen only in one of the 3 characteristics studied. A possible explanation for these latter results is given.
