The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons. Parkinson's disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta.

Sambucus nigra is a species complex of flowering plants in the family Adoxaceae native to most of Europe and North America. Common names include elder, elderberry, black elder, European elder, European elderberry, and European black elderberry. It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations. The plant is a very common feature of hedgerows and scrubland in Britain and northern Europe, but is also widely grown as an ornamental shrub or small tree. Both the flowers and the berries have a long tradition of culinary use, primarily for cordial and wine. The Latin specific epithet nigra means "black", and refers to the deeply dark colour of the berries.
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. Robertson stated that he had not seen the form outside Ireland. It was listed by Loddiges (1830) as Ulmus nigra, and described by Loudon in Arboretum et Fruticetum Britannicum (1838), as Ulmus montana nigra. 'Nigra' is not mentioned in either Elwes and Henry's or Bean's classic works on British trees.
