The first detailed archival study of the indigenous populations of the early historic period in the Lower Rio Grande Valley of Texas and Mexico. Certain to become a standard reference in its field, Indians of the Rio Grande Delta is the first single-volume source on these little-known peoples. Working from innumerable primary documents in various Texan and Mexican archives, Martín Salinas has compiled data on more than six dozen named groups that inhabited the area in the sixteenth through the eighteenth centuries. Depending on available information, he reconstructs something of their history, geographical range and migrations, demography, language, and culture. He also offers general information on various unnamed groups of indigenous people, their lifeways, and on the relations between the them and the colonial Spanish missions in the region. “The scholarship is nothing short of superb . . . Salinas has produced the definitive work on the area, which has been needed for years.” —Rudolph C. Troike, Professor, Department of English, University of Arizona

The Río Mayo region of northwestern Mexico is a major geographic area whose natural history remains poorly known to outsiders. Lying in a region where desert and tropical, northern and southern, and continental and coastal species converge, it boasts an abundance of flora first documented by Howard Scott Gentry in 1942 in a book now widely regarded as a classic of botanical literature. This new book updates and amends Gentry's Río Mayo Plants. Undertaken with Gentry's support and participation before his death in 1993, it reproduces the original text, which appears here with annotations, and contains information on over 2,800 taxa—more than twice the 1,200 species first described by Gentry. The annotated list of plants includes information on distribution, habitat, appearance, common names, and indigenous uses. A new introduction provides historical background and a review of geography and vegetation. It also describes changes to the land and river wrought by agricultural development, expanded grazing, and lumbering. Throughout the text, the authors have endeavored to provide information on Río Mayo vegetation while emphasizing local knowledge and use of plants, to preserve Gentry's field-oriented focus, and to present botanical information with Gentry's exuberance and style. Río Mayo Plants has long stood as a book that displays a scientist's love of the English language, his fondness for native peoples, and his eye for beauty in nature. This updating of that work fills a gap in the botanical literature of this portion of North America and will be useful not only for botanists but also for biogeographers, taxonomists, land managers, and conservationists.
