rac03 | The Racomitrion lanuginosi von Krusenstjerna 1945 was described in a broad meaning including syntaxa from acidic rock and shallow soil on rock outcrops. The type association of this alliance is the Racomitrietum lanuginosi von Krusenstjerna 1945, the original diagnosis of which shows ambiguity in terms of species composition accomodating species typical of both, acidic rock and stabilised soil. Marstaller (2006) classified the alliance Racomitrion lanuginosi in the class Ceratodonto-Polytrichetea and order Polytrichetalia piliferi. (H. Bültmann).
