Élie Marchal

Élie Marchal (1 March 1839, in Wasigny – 19 February 1923, in Gembloux) was a Belgian botanist and mycologist.

From 1861 to 1871, he was a middle-school teacher in the communities of Virton, Ath, Visé and Maeseyck. From 1871 to 1879 he was associated with research done at the Jardin botanique des Bruxelles. Additionally, from 1872 until 1899, he worked as a lecturer at various horticultural and teacher schools. In 1899 he retired to Gembloux, where he worked closely with his son, botanist Émile Marchal (1871–1954).

He was the binomial author of numerous species within the flowering plant family Araliaceae. The mycological genera Marchaliella and Marchalia are named in his honor, the latter genus being circumscribed by Pier Andrea Saccardo.

He edited two exsiccatae, namely Les Glumacées de Belgique (1869–1871) with C. A. Cogniaux and Cryptogames de Belgique (1882).
