Abstract
The occuring and developping along the Black Sea shores of
Desmotrichum undulatum (J.Ag.) Reinke, one of the brown seaweeds, 
is described in this paper. Some of the ecological patterns
(substrate, hydrodynamics, light, temperature and salinity), as
well as pollutant agents that are implied in Desmotrichum undulatum 
biology are described. The great biomasses produced in April-May
on the rocky shores by this alga, had a high significance.
