Is this species of tree nationally rare in the UK?
Only found on Arran, according to Wikipedia.
Edit: and according to Stace 3.
... in the wild is restricted to a few (2, if I recall correctly) glens on the Isle of Arran. There are records from 7 tetrads, but only from 4 this century.
It is cultivated in a few collections, such as RBGE Leith and Brodick Castle.
Sorbus pseudofennica has genome composition AAB (that is two whitebeam and one rowan genomes); the other Arran endemics Sorbus arranensis and Sorbus pseudomeinichi have genomes AABB and ABBB respectively. Sorbus intermedia is a tetraploid with whitebeam, rowan and wild service tree genomes - I haven't been able to find out which has two copies.
the genomic combinations need correcting - its tetraploid whilst the others are triploid see my BSBI Sorbus handbook please where it is spelt out in detail
Yes, Tim, I believe so. It is broad and we cannot see the underside but....
The Wiki and EOL links are very annoying for Sorbus intermedia agg.
lavateraguy's may well be a safer bet and well explained too but I live dangerously sometimes!

No, intermedia agg is not a safer bet, I am sure it is intermedia sensu stricto
