The Convolvulaceae, with an estimated 84 species, is the seventh largest family in the state of Sonora, Mexico (Costea et al., 2012; Felger et al., 2012). When we were getting the study ready for the publisher, the length of the articles made us realize that inclusion of illustrations would be limited. Therefore, we decided to create this companion catalog illustrating the species in Sonora. To help people recognize these diverse plants, ranging from diminutive annual vines to trees, multiple illustrations are The result of this study is the most detailed and complete investigation of the family in any of the northern states of Mexico. While we and our colleagues have taken many of these photographs within Sonora, we include others taken elsewhere to illustrate the species.

We each started studying plants in Sonora at different times. We have, however, been collaborating on this family for more than two decades. Most of Dan’s studies of the family, starting in 1966, were confined to southern Mexico and farther south into northern South America until about 1989 when he was on sabbatical at Arizona State University in Tempe working on the Convolvulaceae for the revised flora of Arizona. That year he began working with Richard and Tom. Richard has been botanizing in Sonora since high school and collecting herbarium specimens there since he was a freshman at the University of Arizona. He and Dan have collaborated on convolv papers, including the description of the Sonoran endemic Ipomoea seaania. His convolv specimens have been shared with Dan and Mihai. In the early 1990s Tom began sending even more of his Convolvulaceae collections to Dan for identification and in 2005 he sent his Cuscuta collections, started in 1996, to Mihai. Mihai began studying Cuscuta from the region in 2004, building on his extensive research on the genus. As curator of the Herbario de la Universidad de Sonora (USON), Jesús has been botanizing in the state for several decades, including convolv collections.

The result of this study is the most detailed and complete investigation of the family in any of the northern states of Mexico. Moreover, the results surprised even us by including almost as many species as known from Veracruz and states to the south in Mexico. July 30, 2012.
