The phytodermology on leaf and the stem anatomy were studied in Helianthemum croceum (Desf.) Pers., H. camum subsp. nebrodense (Heldr.) Arcang. and H. cinereum (Cav.) Pers.. In particular, the characters taken into account concern presence of trichomes, heterogeneity of chlorenchyma, presence of glandular hairs, epidermal foliar parameters by scanning electron and light microscopy, leaf architecture as well as stem and flower bud structure.
