1036 Saxifraga paniculata Mill.

Syn.: S. aizoon Jacq.

This variable species is pronouncedly calciphile. In Caucasus and adjacent areas subsp. cartilaginea (W illd.) Engl. & lrmsch. occurs. The northernmost population in Norway is described as subsp. laestadii Neum. Somewhat differing, too, are the populations in N. America, described as subsp. neogaea (Butters) Hult. S. paniculata s. lat. belongs to the amphiatlantic plants (Hultén, Amphi-atl., p. 44 and map 25). Cf. also Meusel et al. 1965, map p. 204.
