The map tentatively shows the distribution of this Eurasiatic species ( or subspecies of E. mamillata according to Strandhede in Opera Bot. 10:2, Lund 1966). Its distribution is on the whole incompletely known. The map is in urgent need of revision. See further Walters in Watsonia 5/1961, p. 329-335.
