Does anyone know what this plant is? I saw it along the edge of a trail in sandy soil at Goose Island State Park in Texas.
My wild guess, it is some kind of Phacelia. These are close but not identical species: P. demissa - http://swbiodiversity.org/imglib/seinet/Hydrophyllaceae/photos/Phacelia-demissa-FL-web-N36.jpg P. parishii - http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0406+0574 P. gymnoclada - http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+1209+2190 P. pulchella - http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0105+2103
