Crataegus laevigata x monogyna (C. x media)
A shrub or small tree of deciduous woods, scrub, and hedgerows on a wide range of soil types. Crosses between the species are as fertile as crosses between two plants of the same species. The hybrid is fully fertile and very variable, partly because of its ability to backcross to the parents. Lowland.
This hybrid can occur in the absence of C. laevigata, but presumably as a native only in sites where the latter species formerly occurred. The distribution closely matches that of C. laevigata, except in N.E. Ireland where the hybrid was widely planted in the 19th and 20th centuries from material derived from English stock.
Frequent in those areas of Europe where both parents occur.
