Material of Sorbus aria-like plants from the Wye Valley with acutely-lobed leaves has been investigated using comparative morphology and reproductive fertility, which show that at least some such plants are S. aria introgressed with S. torminalis. The introgression was found to occur only from S. aria into S. torminalis. The primary and introgressed hybrids have lower pollen and fruit fertility than the parents. The parents show widespread overlap in distribution in southern Britain but… Expand
