Etymology

Named for American cactus collector Dr Josiah Gregg (1806-1850). Engelmann: “The specimens sent for cultivation by Dr. W. [Wislizenus] were unfortunately dead when they arrived here, and neither flower nor fruit had been obtained; but Dr. Gregg has collected the same species near Cadena, south of Chihuahua, in flower, from which I completed the description. I could not have given it a more appropriate name than that of the zealous and intelligent explorer of those far off regions.”
