S. perennis L., Sp. PL 406 (1753). Perennial or perhaps sometimes annual or biennial with procumbent to erect stems up to 25 cm. Leaves up to 13 mm. Inflorescence lax to fairly dense, the upper leaves not exceeding the flowers. Perigynous cup 1.2-2 mm in fruit. Sepals equalling to 2 x longer than the perigynous zone in fruit, spreading to erect, ± oblong, broadly rounded at the apex, with conspicuous scarious margins about as broad as the green central part. The whole flower 3-6 mm in fruit. Fl. 4-6. 1. Compact, often subcaespitose, with procumbent or ascending stems 2-10(-18) cm, internodes up to 10(-14) mm, usually not purple; flower 3-4.7 mm in fruit subsp. marginatum 1. More robust and elongate with ascending to erect stems mostly 10-25 cm, the longer internodes 10-25 mm, usually conspicuously dark purple; flower 3.8-5 mm in fruit subsp. dichotomus subsp. marginatus (Guss.)

This species is known only from western Turkey except for two collections from vilayet Çoruh in extreme N.E. Anatolia. One of these two collections appears to have the erect habit and purple stems of subsp. dichotomus, while the other appears to have a procumbent habit and no purple colouration, as in subsp. marginatus. They are consequently here referred to different subspecies, but further observations are required.
