E. arenarius corolla, Roosevelt Co., NM, Strahan 473

by Bob Harms 

The corolla of E. arenarius is lavender, similar to that of E. nuttallianus, but differs in fading to yellowish with age. No collections had flowers that had not already changed. Some collections had no flowers or only quite old flowers. I am hoping to get a photograph from Robert Strahan, who may be the only person to have photographed this species.
