Abstract: "[Investigators] revisit Stebbins' views on the frequency of hybridization, the evolution of hybrid sterility, and the evolutionary importance of transgressive segregation, introgression, and homoploid hybrid speciation in the context of contemporary evidence. Floristic surveys indicate that ∼10% of plant species hybridize, suggesting that natural hybridization is not as ubiquitous as Stebbins argued." |

P.1248 left column 2nd paragraph: "Although the ubiquity of hybridization across plants was accepted into the 1990s (Raven, 1976, Whitham et al., 1991), surveys of floras suggest that this is not the case, with estimates of the proportion of plant species that hybridize ranging from ∼3% in the Concord Township flora in Massachusetts (BNID 113465) to ∼25% for the flora of the British Isles (BNID 113465), with an overall frequency of 0.09 hybrid combinations per nonhybrid species (primary source)." |
