Everyone with a professional interest in the flora of Texas will welcome this checklist of the vascular plants. This comprehensive list also includes crops, persistent perennials, and naturalized plants and encompasses over 1,000 changes to the previous (Hatch, 1990) checklist. The authors have arranged this checklist phylogenetically by classes following the Cronquist system. Several features make this checklist especially useful. Chief among them is the relative synonymy (name history). An extensive index makes current classification and correct nomenclature readily accessible, while the botanical bibliography is the most extensive ever compiled for Texas. The authors also note which plants have been listed as threatened or endangered by the Texas Organization of Endangered Species, which are designated as Federal Noxious Weeds, and which have been chosen as state tree, flower, fruit, etc. by the Texas Legislature.

This study of the vascular plant taxa in this region includes keys, descriptions, habitats, distributional data, and pertinent synonymy to every vascular species without cultivation in the southeastern United States. The Asteraceae is the largest family o

Montana is the fourth largest state in the United States. It includes portions of both the Northern Great Plains and the Rocky Mountains. Vegetation of Montana is diverse, due primarily to the size of the state as well as great topographic relief which provides strong variation in environmental factors. Montana has a relatively large flora for a northern continental region due to being at the intersection of the Cordilleran, Great Plains, and Boreal floristic provinces. This book is a comprehensive field guide to the more than 2,500 species of Montana's vascular plants. It contains descriptions as well as habitat and distribution information based on specimens housed at the state's two major herbaria. Portraits or illustrations of diagnostic structures are provided for nearly one-third of the species.
