Erzberger, P.; Schröder, W.: The genus Schistidium (Grimmiaceae, Musci) in Hungary

Distribution: S. flaccidum was known in Hungary from two locations, one near Pomáz in the Visegrád Mts and one between Nagymaros and Zebegény, on the left side of the Danube. Phytogeographically this site, Mt Szentmihály or Mt Ördög, belongs to the Visegrád Mts (BOROS 1968). Here the plant was apparently found only once (SZEPESFALVI 1941), and only a single, very small specimen exists in BP, whereas at the Pomáz site, in the year 2000, the population was still present and vigorous. From this site, numerous collections exist, the oldest from 1921 (leg. Győrffy). S. flaccidum grows on the treeless, sunny slopes of the hill Kis Csikóvár, in fissures of andésite rock outcrops. Recently, B. Papp discovered a third locality at Szarvaskő in the Bükk Mts. Fig. 20.
