Description
Sorbus wilmottiana is a small tree or shrub, up to 10m in height. It is often multistemmed, with rather upright branches.[3]
Distribution
This species is confined to the Avon Gorge, in SW England; less than 100 individuals are known.[4]
Ecology and Evolution
Sorbus wilmottiana appears to be shade intolerant, growing in rocky scrub and grassland on shallow, mildly acidic soils.[5] Sorbus wilmottiana arose from a cross between Sorbus aria and Sorbus porrigentiformis.[6]
gollark: It actually seems like the whole setup handling them is deliberately byzantine and overcomplicated to stop this sort of thing.
gollark: I am annoyed by how hard Amazon makes it to get the ebooks I bought (realistically, bought a license to legally) out of their walled garden and onto Calibre in some sort of actually standard format. Apparently I can't get any sort of usable files off the Android app, and I've lost my actual Kindle hardware, so I've had to download some ancient version of their Windows client and run it in Wine.
gollark: Yes, this does seem to go against the previously established thing of only Ennesby being able to do that.
gollark: It's Australia. It's probably an actual kraken.
gollark: It *would* reduce the habitat available to the many, many very horrible animals there.
