Meyer var. listoniae (Vis.) Fröder., op. cit. 51, f. (1932). Ic: Fröder., op. cit. 7: t. 27 (1932). Erect perennial, 10-40 cm, glabrous or glandular-papillose above; sterile shoots at first bulbiferous, whitish and subterranean, later rising to the surface and forming green rosettes from which the flowering shoots arise. Aerial leaves at base of stem ovate-oblong, 10-40 x 8-15 mm, obscurely crenate to entire, obtuse, sessile, becoming smaller further up the stems and acute. Flowers 5-merous, sessile; sepals 5-6 mm, acute; petals pink or red, (7-)8-10 mm; stamens 10; follicles glabrous though minutely papillose, spreading. Fl. 7-8. Rocky places, under Juniperus, etc., s.l-2160 m. Type: [Soviet Azerbaijan: Talysch] in campis siccis altiorum montium Talüsch versus pagum Perimbal, 1000 m, C.A.Meyer. Anatolia, scattered.

The distinction between S. listoniae and S. obtusifolium largely appears to be in the size of the plants; the former is considered to be larger than the latter. The material of S. listoniae (including S. proponticum), however, agrees well with the photograph seen of the type of S. obtusifolium, at least vegetatively. Other differences cited, such as the indumentum of the ilowering stems and shape of the sepals, appear to be fairly trivial though more material from E. Anatolia and the Caucasus is required before, their constancy can be ascertained. In view of the doubts concerning the status of the taxa included here, I have preferred to take a wide view of S. obtusifoliurn.
