Jean-Maurice Casimir Arvet-Touvet was a French botanist born in Gières.
His early botanical investigations involved species native to Dauphiné, publishing in 1871 Essai sur les plantes du Dauphiné. Subsequently, he devoted his energies to research of the genus Hieracium. With his friend, Marie Clément Gaston Gautier, he conducted studies of Hieracium found in the Pyrenees and the Iberian Peninsula. With Gautier he issued a 20 booklet exsiccatae of the genus.
During the last few years of his life he was involved with publication of Hieraciorum praesertim Galliae et Hispaniae catalogus systematicus.
