Karpatiosorbus devoniensis is known by the English name of Devon whitebeam and formally as Broad-leaved Whitebeam. When the fruit was reported as sold at Barnstaple Pannier Market  the name French Eagles was used, apart from 1929 when they were reported as eagle-berries. When the trees were reported as seen growing wild on botanical walks they were referred to as French Hails (once each as French hail and French Hales). Broad-leaved white-beam, which was the common name until Devon Whitebeam took over, was used once in 1907. The term Otmast was used once as a pet name, as its true identity was not known. It is a species of whitebeam, trees and shrubs in the family Rosaceae. It is endemic to the British Isles, growing wild in areas of Devon, Cornwall, Somerset and south-east Ireland as a native and north-east Ireland as an introduction.

It probably did not exist before the last ice age, arising from a hybrid between Sorbus torminalis, the wild service tree, and another species of whitebeam. It is a close relative of the no parking whitebeam, Karpatiosorbus admonitor, and two other British natives and around 40 species in Europe.
