There are two subspecies: Asphodelus bento-rainhae ssp. bento-rainhae is found in Portugal and Asphodelus bento-rainhae ssp. salmanticus is present in Spain. The two subspecies are not closely related genetically.
This species is classified as Vulnerable D2, as it is only found in four locations (two in Portugal and two in Spain), in a very tiny area of occupancy. If, despite conservation actions, the quality of its habitat was to decrease further, this species would qualify for an Endangered category.
