Jean Charles Marie Grenier

Jean Charles Marie Grenier (French pronunciation: [ʒɑ̃ ʃaʁl maʁi ɡʁənje]; 1808–1875) was a French botanist and naturalist who was a professor to the Faculty of Sciences at Besançon.

At Besançon, he taught classes in natural history, zoology and botany, being appointed doyen of the school in 1869.

[1] Grenier is credited with the description of hundreds of botanical species, many of them in collaboration with Dominique Alexandre Godron (1807–1880), a professor of natural history at Nancy.

With Prof. Godron he published a three-volume work on French flora called Flore de France (1848–1856).

Grenier was also author of Flore de la châine jurassique (Flora of the Jura Mountain chain) (1865–69).
