Neogaya is a monotypic genus of flowering plants belonging to the family Apiaceae.

[2] It contains just one species, Neogaya simplex,[1] and can be found in Europe, the Alps, the western and southern Carpathians, former Yugoslavia, Belarus.

[3][4] After flowering it produces a seed capsule or 'fruit', which like other members of the Apiaceae family, is polachenarium, a dry schizocarpic fruit consisting of monocarps separating from a longitudinal central axis (columella or carpophore), often remaining attached to the axis at maturity.

[5] The genus name of Neogaya is in honour of Jaques Étienne Gay (1786–1864), a Swiss-French botanist, civil servant, collector and taxonomist.

[8] The Latin specific epithet of simplex means simple or unbranched from simplicissimus.

[3] It is found in Europe, within the countries of Austria, Czechoslovakia, France, Germany, Italy, Romania, Poland, Switzerland and Yugoslavia.
