Besch.

Émile Bescherelle (3 January 1828, Paris – 26 February 1903) was a French botanist and bryologist.

Bescherelle is known for his analysis of bryological species from diverse locations that included the French West Indies, the Mascarene Islands, Paraguay, New Caledonia, et al. In 1882 with phycologist Paul Auguste Hariot (1854–1917), he took part in a scientific expedition to Cape Horn.

The genus Bescherellia is named in his honour by Jean Étienne Duby (1798-1885).

In addition, he was a collaborator towards Narcisse Théophile Patouillard's publication of Catalogue raisonné des plantes cellulaires de la Tunisie.
