S. erythraeum Griseb. , Spicil. Fl. Rumei. 1: 326 (1843), described from W. Macedonia and recorded elsewhere in the Balkan peninsula, is a plant of obscure affinities, perhaps related to 19. It differs in its dwarf habit (c. 2 cm), small leaves (c. 2- 5 mm), mucronate, reddish-purple petals, and erecto-patent follicles with longer styles. S. horakii Rohlena , Acta Bot. Bohem. 2: 19 (1923), described from Crna Gora, has been wrongly identified with 20 and with 48 but seems to be intermediate between 16 and 19, resembling the latter in habit and leaf, but with mucronate petals, often streaked with red, and fairly long styles. Plants referable to this complex are also recorded from Albania.
