I saw a roadside Sorbus tree today. Of the Mountain Ash type.

The berries were yellow and the leaves were a delightful reddish brown.
It was quite striking.

Can anyone suggest which species it was?

There's a lot of different rowans. (50 species or so, IIRC.) However
one of the yellow-fruited forms is the cultivar 'Xanthocarpa' of the
native Sorbus aucuparia. But the specimen I photographed last month at
NT Wallington is more orange- than yellow-fruited.

I've been through my digital image collection, and other
yellow-fruited forms are Sorbus 'Sunshine' (also somewhat orange) and
Sorbus 'Joseph Rock'.

Joseph Rock is very upright in growth. If Neil saw the same type as I
noticed over the weekend, it's a much more rounded shape. Quite
spectacular, an overall image of red, embedded with clusters of pure
yellow fruits.

'Sunshine' is also upright in growth. The 'Xanthocarpa' I saw had a
rounded crown, but Sorbus aucuparia can also be upright in growth, and I
wouldn't be confident that 'Xanthocarpa' has a consistent habit.
