Branches, stems, and spines are densely covered in short erect hairs, which give the species a silvery colour. Spines are thin and straight or sometimes slightly arched. The calyx is typically 7.5 to 8.5 mm long.Taxonomy and systematicsUlex argenteus is a diploid species. Ulex canescens, and Ulex erinaceus and Ulex subsericeus have been included in Ulex argenteus in the past, as subspecies or synonyms. However, phylogenetic evidence suggests they are not closely related to U. argenteus.Distribution and habitatThe species is distributed in southern Portugal, growing in both metamorphic and calcareous hills.ConservationThe species has a narrow distribution range but remains common in suitable habitat. As a result, it has been assessed as Least Concern.
