Caucasian Wingnut, (Pterocary fraxinifolia) The Caucasian Wingnut is native to the region from the Caucasus Mountains to Iran  and was introduced into cultivation in 1782. This is an uncommon tree with few specimens in Ireland. The pinnate leaves are large – to 60 cm, with up to 21 leaflets either side of a common stalk.  In autumn 25 – 30 cm long pendulous green catkins hang beneath the foliage, each fruit surrounded by a circular wing, hence the common name. The scientific name is derived from the Greek words for wind ‘ptero’ and nut ‘carya’  and  ‘fraxinus’ the scientific word for the common Ash and ‘folia’ leaf/ leaves. (Source: Dr Mary Forrest, UCD).
