"Lemonvine is not the only wild plant profiled in Cacti of Texas that might tempt gardeners. In fact, this so-called field guide could easily become a gardener's wishbook." --William Scheick, Texas Gardener's Seeds 6/4/2008 "Profiles with distribution maps and color photos describe all the state's genera with keys to the Trans-Pecos species." --SciTech Booknews, 6/2008 "The manual, with its beautiful full-color photographs and distribution maps, will be important to professionals in national and state park resource interpretation, wildlife biology, ecology, range management, and environmental consulting." --Sirreadalot.org, 4/2008 "Powell & Weedin converted their extraordinary 2004 treatise Cacti of the Trans-Pecos and Adjacent Areas into an equally superb abridged version, a.k.a. field guide." --Root Gorelich, Plant Science Bulletin 2008
