The mineral composition of Myriophyllums spicatum L. (Eurasian water—milfoil) and its aquatic environment were investigated to determine the relationship between ionic contents in the plant and in the water. Systematic samplings were made in several areas. The species was growing in a wide range of environmental situations. Normal—appearing specimens were collected at water temperatures ranging from 0.2 to 30°C. Salinities varied from 0.05 to 16.4 ppt. Each of the estimate collecting sited fluctuated about 7 ppt during the experimental period. The fresh—water pond varied between 0.05 and 0.20ppt. The pH values ranged from 5.8 to 9.5 with alkaline waters predominating at four of the five collecting stations. M. spicatum was capable of regulating salt intake independent of concentrations in the aquatic environment.
