Many individuals have generously contributed photos and plant material, most prolifically among them: Paul Berry, Xavier Cornejo, Douglas Daly, Robin Foster, Lúcia Lohmann, Paul Maas, Scott Mori, Mike Nee, Marie Frangoise Prevost, Karen Redden, Wayt Thomas, and the Igapó Guide Team (http://ecologia.ib.usp.br/guiaigapo/equipe.html), which generously supplied the banner photo of Swartzia macrocarpa.

Our continuing effort to produce a comprehensive phylogenetic monograph of Swartzia is generously funded by the National Science Foundation (DEB-0918498). Funding for B. Torke’s past work on Swartzia was provided by the National Science Foundation (DEB-03009162), the Deep Time Project, the Botanical Society of America, the American Society of Plant Taxonomists, the Rupert Barneby Award of the New York Botanical Garden, a grant from the Mellon Foundation to the Missouri Botanical Garden, and a postdoctoral fellowship from the Academy of Natural Sciences. We are grateful to the Missouri Botanical Garden, Washington University, the Academy of Natural Sciences, the Jardim Botânico do Rio de Janeiro, and the New York Botanical Garden for previous and ongoing institutional support and access to their research facilities.

Development of this website been aided immeasurably by the skill, dedication, and generosity of the staff of the Herbarium and Library of the New York Botanical Garden. B. Torke is particularly grateful to Barbara Theirs, Director, and Jackie Kallunki, Associate Director of the Herbarium, for their commitment to making specimen data available online and to Melissa Tulig, Bioinformatics Manager, for helping him to design and launch the Swartzia Pages. This website is very much modeled on Scott Mori’s Lecythidaceae Pages (https://sweetgum.nybg.org/science/projects/lp).
