This little-known taxon from the L. polytropa group occurs on slightly calcareous silicates or limestones at high elevations. Sudeten populations grow both on relatively dry and damp overhanging rocks, occasionally irrigated rocks. In general, it is a rare species, reported only from few higher European mountain ranges. In the Czech Republic, its occurrence is limited to the Krkonoše Mts and the Hrubý Jeseník Mts, where it can be found mainly in glacial cirques. Probably the richest population in our country occurs in the vast cirque of Velká kotlina in the Hrubý Jeseník Mts.taxonomic classification:
