--><p>The vernacular name of <i>Astrophytum asterias</i>, star-peyote, reflects its superficial similarity to peyote, <i>Lophophora williamsii</i>, which has very soft, uniformly pale blue-green stems quite unlike the hard, speckled, almost shiny, green stem surface in <i>A. asterias</i>. <i>Astrophytum asterias</i> is extremely rare and localized north of Mexico, presently known only from Starr County, Texas.</p>
