The first description of H. cedretorum as a separate taxon was made by Auguste Pomel in 1874, when he described "Endymion cedretorum" in his work Nouveaux matériaux pour la flore atlantique, based on plants growing on Djebel Endate in Algeria.[1] The same species was later described by Jules Aimé Battandier as "Endymion patulus subsp. algeriensis", and by Alfred Charles Chabert as "Endymion kabylicus".[1] Both Pomel's name and Battandier's name have been treated as infraspecific taxa (subspecies or variety) within the species Hyacinthoides hispanica, but it is now regarded as a separate species,[1] and was placed in the genus Hyacinthoides in 2009.[3]
