This user-friendly field guide is the essential reference for everyone interested in South Texas flora. Nature enthusiasts, farmers and ranchers, professional botanists, and others will appreciate its abundant photographs and short descriptions that provide a simple means of identifying the plants that grow naturally in Cameron, Hidalgo, Willacy, and Starr counties. Covering the almost three million acres of southernmost Texas known as the Lower Rio Grande Valley (LRGV), the book showcases the diversity in this region"s juncture of subtropic, temperate, coastal, and desert influences, representing eleven distinct biotic communities. More than 800 species (excluding grasses), two thirds of the species that occur in this region, are described in Plants of Deep South Texas. Wildflowers, woody and broad-leaved plants, ferns, and algae are profiled and pictured in one place, some for the first time. In addition, the authors provide comments that include indispensible information that can"t be seen in a photograph, such as the etymology of the scientific name, the use of the plant by larval butterflies, and species value from the human perspective. The authors also provide a glossary of terms as well as an appendix of butterfly and moth species mentioned in the text. Plants of Deep South Texas is an indispensible field guide by two of the best known experts on the region"s native flora.
