Auguste Adolphe Lucien Trécul (8 January 1818 in Mondoubleau – 17 October 1896 in Paris) was a French botanist.
[1] His interests later changed to botany, and in 1848–50, on behalf of the Muséum national d'histoire naturelle and the Ministry of Agriculture, he conducted scientific research in North America.
In 1866 he became a member of the Academy of Sciences (botany section), and during the following year, was awarded the Légion d'Honneur.
He published important papers on the structure of different members within the botanical family Nymphaeaceae, and was the author of a significant monograph on Artocarpeae.
[5][2] The plant genus Treculia (family Moraceae) was named in his honor by Joseph Decaisne.
