Aria wilmottiana, commonly known as Willmott's whitebeam,[2] is a species of whitebeam in the family Rosaceae. It is endemic to England, and is found in the Avon Gorge, in Somerset and Gloucestershire. It is threatened by habitat loss.

Description

[edit]

Aria wilmottiana is a small tree or shrub, up to 10m in height. It is often multistemmed, with rather upright branches.[3]

Distribution

[edit]

This species is confined to the Avon Gorge, in SW England; less than 100 individuals are known.[4]

Ecology and evolution

[edit]

Aria wilmottiana appears to be shade intolerant, growing in rocky scrub and grassland on shallow, mildly acidic soils.[5] Aria wilmottiana arose from a cross between Aria edulis and Aria porrigentiformis.[6]
