A Southwest Book of the Year * 2005 Southwest Book Award "[A] monumental study." --Review of Texas Books "A reliable and handy general reference for those with an interest in cacti inside and outside this region. Recommended." --Choice "These authors have . . . provided the world with the much needed scientific clarification on this family of succulent plants that humans have loved and hated for thousands of years." --Sida "Information: Wow! . . . For both lay readers and for researchers looking for lots of data about the cacti of this rich flora, this book offers fascinating details presented in a very readable fashion." --Cactus and Succulents Journal "This will be the standard reference for decades to come."--Southwest Books of the Year Of the 132 species and varieties of cacti in Texas, about 104 of them occur in the fifteen counties of the Trans-Pecos region. This volume includes full descriptions of those many genera, species, and varieties of cacti, with sixty-four maps showing the distribution of each species in the region. The descriptions follow the latest findings of cactus researchers worldwide and include scientific names; common names; identifying characters based on vegetative habit, flowers, fruit, and seeds; identification of flowerless specimens; and phenology and biosystematics. The introduction--full of details about the biology and morphology of the family Cactaceae, the uses of cacti, and the horticulture and conservation of cacti--is an important reference for general readers. More than three hundred beautiful full-color photographs of the cacti in flower and in fruit, all cross-referenced to their description in the text, highlight the book. A glossary of cactus terms, an exhaustive list of literature, and a thorough index complete the book.
Since 1987, more than 225 species have been identified and described as endangered, imperiled, or declining. Complete with photographs, line drawings, and county maps, this book describes the officially listed, candidate, and species-of-concern plants in Texas. Individual accounts include information on distribution, habitat, physical description, flowering time, federal and state status, similar species, and published references.
Endangered and Threatened Species - Reclassifying Tobusch Fishhook Cactus From Endangered to Threatened and Adopting New Scientific Name (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition) The Law Library presents the complete text of the Endangered and Threatened Species - Reclassifying Tobusch Fishhook Cactus From Endangered to Threatened and Adopting New Scientific Name (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition). Updated as of May 29, 2018 We, the U.S. Fish and Wildlife Service (Service), reclassify Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii; currently listed as Ancistrocactus tobuschii), from endangered to threatened on the Federal List of Endangered and Threatened Plants. This determination is based on a thorough review of the best available scientific and commercial information, which indicates that the threats to this plant have been reduced to the point that it is no longer in danger of extinction throughout all or a significant portion of its range, but it remains threatened with becoming endangered within the foreseeable future. In addition, we accept the new taxonomic classification for Tobusch fishhook cactus as the subspecies Sclerocactus brevihamatus ssp. tobuschii.
