Editorial Note

The text below is from New Trees (Grimshaw & Bayton 2009) who discussed this taxon under the name Sorbus takhtajanii. We have created this hybrid article – New Trees text under the correct modern name, with appropriate synonymy – whilst we await sponsorship to enable a full revision of this genus to be written. We are re-organising the Sorbus sensu lato articles in this way to enable a new revision of Sorbus sensu stricto to commence in 2023, and to bring the nomenclature of this complex group of plants up to date in line with modern treatments.

Sorbus takhtajanii is represented in several British arboreta and is reasonably distinct on account of its dark green leaves with a bright white underside. The leaves are strongly toothed in their upper half. It is one of the Armenian species whose introduction is described above. All of them have proved to be relatively slow-growing, having champions of no more than 4–5 m (TROBI) as yet.
