This investigation presents ecological characteristics of Betula medwediewii Regel, a relict woody species and Veratrum album L., an important medicinal plant, both naturally distributed in Western Transcaucasia. Elemental analyses in plants and soils was carried out and soil-plant relationships in the leaves evaluated. The findings obtained from leaves of B. medwediewii revealed that nitrogen, phosphorus, potassium, calcium, iron and copper concentrations were within the limit values in contrast to those of, magnesium and nickle, which were higher. It was also seen that in the lower cauline leaves of V. album, the nitrogen, phosphorus, potassium, calcium, magnesium and copper showed normal values while iron and nickle concentrations exceeded the normal levels. In general, the concentrations of all elements investigated in the soil samples of both species were low.
