title: Arsenic Tolerance in a Population of the Grass Andropogon scoparius Michx.
abstract: Samples of Andropogon scoparius Michx. collected on an arsenic mine exhibited a wide range of tolerance to arsenic in solution, whereas plants of the same species growing in uncontaminated soil showed no tolerance. Arsenic tolerance must be an evolved character under genetic control. Furthermore, the degree of tolerance is related to the amount of arsenic in which the plant was growing.
