After doing some research, and thanks to the help of friends, it would appear that all sand asters in the area are actually the rare Del Mar Mesa sandaster (Corethrogyne filaginifolia var. linifolia) but it seems that not all agree whether it is a subspecies – which would explain that both sightings of the Common sandaster and the Del Mar Mesa sandaster are reported for the area.
