Although nationally scarce, Devon Whitebeam has one of the most robust populations among the whitebeam microspecies, with 1,500 estimated specimens.

Endemic to south-west England and in Ireland, growing on moderately acid soils in the lowlands. It is sometimes locally frequent, especially in woodland edges and hedgerows (despite being regularly flailed) in north Devon.
