Roadside Pictures in Winkler County, Texas, 23 June 2013.

I had a chance to go with my daughter to the lower Texas Panhandle in June, 2013, with the hope of finding living specimens of E. arenarius. We were not able to get access to private land, so we spent half a day walking the roadsides near Kermit, but because of the severe drought in the area, we didn't find any. Some of the plants in these pictures look fresh, since there had been recent rains. [click to enlarge]
