The legume volume of FNA is dedicated to Jim Zarucchi, a prominent legume systematist who worked at the Missouri Botanical Garden from 1984 to 2019. Jim was heavily involved in the FNA project, serving as Editorial Director of FNA and as lead editor of Volume 10, Magnoliophyta: Proteaceae to Elaeagnaceae and Volume 11, Magnoliophyta: Fabaceae, until his untimely death in 2019. A tribute to Jim was published in the Bean Bag, Issue 67 in 2020.

Volume 11 is the twenty-third volume to be published in the planned 30-volume Flora of North America North of Mexico (FNA) series, which presents for the first time, in one published reference source, information on the names, taxonomic relationships, continent-wide distributions, and morphological characteristics of all plants native and naturalized in North America north of Mexico.
