Descriptions of clades and genera. In the descriptions of genera, characters are not mentioned consistently if the genus fits the "usual" condition for the family (e.g., hairs medifixed or submedifixed, leaves opposite, unlobed, and entire-margined, flowers all chasmogamous and bisexual, sepals 5, petals 5 and clawed, anthers dehiscing by introrse longitudinal slits, styles distinct). The notes on pollen morphology in the descriptions of genera come, unless noted otherwise, from Lowrie (1982).

Nomenclature. The nomenclature used here is based on the database "Nomenclature of Malpighiaceae" of W. R. Anderson. That database gives extensive information on all validly published names for taxa of New World Malpighiaceae and many taxa of Old World Malpighiaceae.

References. The descriptions, keys, and other information on this website are the work of W. R. Anderson, except where credit is given to another source. The most recent revision of the entire family is that by Niedenzu (1928), and although it is now out of date, it remains an essential resource for the family; it will not be cited separately under each genus. A recent publication gives an overview of the family (W. R. Anderson, 2004), but the numbers of genera and species cited there are already out of date. Many treatments for genera or parts of genera have been published since 1928, and those will be cited under the genera.

Line drawings. Most of the drawings on this website are the work of Karin Douthit; additional drawings were made by H. M. Fukuda, Amanda Humphrey, Melissa Marshall, John Megahan, and Annette Seidenschnur Mahler. Bobbi Angell permitted the use of her drawing of Mezia angelica. All artists are acknowledged in the captions. When drawings were published previously the place of their original publication is given; when unpublished they are cited as © University of Michigan Herbarium, and all rights to those drawings are reserved.

Photographs. The photographs shown here come from diverse sources, noted in the captions. In every case the photographer retains the rights to her or his work.
