Ehrendorfer (l.c.) has treated this taxon as a subspecies of Galium setaceum Lamk. However, in view of the clear cut differences in the shape of the corolla-lobes and the type and the density of the hairs on the fruit, Galium decaisnei Boiss. and Galium setaceum Lamk. are treated as two distinct species. Ascending up to 1500m.
