... a rowan (Sorbus) not an elder (Sambucus).
[Sambucus racemosa has pyramidal inflorescences and infructescences.]
... while the spelling error was a typo (adjacent keys), the identification as Sorbus sp. rather than Sorbus aucuparia is likely to have been intentional.
Photographs can be misleading, but I would say that this has smaller fruits than Sorbus aucuparia as well as different leaves. I'd guess at Sorbus commixta (or Sorbus 'Embley').
Thanks lavateraguy for your (correct) support. I usually spot my many transpositions and fluffs but missed that.
Thanks for the help "thistle" and especially "cicuta58". This time I think "lavaterguy" has hit the nail on the head. Embley doesn't quite right - leaflet size, but Sorbus commixta looks correct.
I have even found a picture with the fruits been held erect: http://www.emotivelandscapes.co.uk/2010/12/some-plants-from-the-autumn/ Also Wikipedia helps quoting "Collins" (can't find my copy) "Plants from Hokkaidō, the Kuril Islands and Sakhalin are sometimes distinguished as Sorbus commixta var. sachalinensis, with larger leaflets up to 9 cm long."
This fits perfectly with the large leaflets I observed on the tree.
Thanks a lot again
