This work represents a phytocoenologic, ecological, bioeconomic and ecoprotectiv study on the vegetation of rocky formations from the class Asplenietea trichomanis (Br.-Bl. in Meier et Br.-Bl. 1934) Oberdorfer 1957.After conducting a 70 phytocoenologic relevées on limestones and silicate rocks from the Codru-Moma Mountains there have been identified a number of five vegetal associations from which only two are examined in this work: Asplenietum trichomanorutae-murariae R. Tx. 1937 and Asplenietum septentrionali-adianti-nigri E. Oberdorfer 1938.The saxicol-sciadophilous phytocoenoses (shady) and sciadophilous-helsciadophilous phytocoenoses (shady-semishady) belonging to groups that we are reffering to were studied in terms of the ecological factors (moisture, temperature and chemical reaction of the soil) and of the distribution of species in the spectrum of life forms and in the spectrum of floristic elements.
