Sorbus devoniensis

Description

Sorbus devonensis is known by the English name of Devon whitebeam and locally as otmast. It is a species of whitebeam tree in the family Rosaceae. It is endemic to the British Isles, growing wild only in areas of Devon, Cornwall, Somerset and Ireland. It did not exist before the last ice age, probably arising from a hybrid between the wild service tree and another whitebeam. It is a close relative of the No Parking whitebeam, Sorbus admonitor, which occupies the same range and is known to hybridise with the Devon whitebeam.
