Summarize this article for a 10 year old
The Wych Elm cultivar Ulmus glabra 'Nigra', commonly known as the Black Irish Elm, was found in the Kilkenny area c.1770 by the father of nurseryman John Robertson of Kilkenny, who later cultivated it.[1] Robertson stated that he had not seen the form outside Ireland. It was listed by Loddiges (1830) as Ulmus nigra,[2] and described by Loudon in Arboretum et Fruticetum Britannicum (1838), as Ulmus montana nigra.[3][4] 'Nigra' is not mentioned in either Elwes and Henry's[5] or Bean's[6] classic works on British trees.

The Späth nursery of Berlin marketed an U. montana nigra in the late 19th century.[7] Späth, like many of his contemporaries, used U. montana both for wych elm cultivars and for those of U. × hollandica.
Though 'Nigra' is sometimes listed as a synonym of 'Cinerea' (see 'Synonymy'), the leaf-descriptions of the two cultivars appear to distinguish them, the latter having leaves recalling those of Exeter Elm.[8] Loddiges' 1830 catalogue lists the two separately.[2]
