The Convolvulaceae, with an estimated 84 species, is the seventh largest family in the state of Sonora, Mexico (Austin et al., in preparation). When we were getting the study ready for the publisher, the length of the article made us realize that inclusion of illustrations would of necessity be limited. Therefore, we decided to create a companion illustrated catalog of the species in Sonora. To help people recognize these diverse plants, ranging from trees to diminutive annual vines, multiple illustrations are presented on this site. While we and our colleagues have taken many of these photographs within Sonora, we include others taken elsewhere to illustrate the species.
It is not possible to know when this project began because we each started studying plants in Sonora at different times. We have, however, been collaborating on this family for perhaps 25 years. Most of Dan’s studies of the family were confined to southern Mexico and farther south into northern South America until about 1989 when he was on sabbatical at ASU working on the Convolvulaceae for the revised flora of Arizona. At that time he began working with Richard and Tom. Subsequently, Tom began sending even more of his Convolvulaceae collections to him for identification. Sometime after that, we discussed and decided that we should do a treatment of the family for Sonora. More recently, in 2006 Mihai began studying Cuscuta from the region. The result of this study is one 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.
