Abstract
Certain ferns and fern allies normally occur on acid soils, whereas others appear to be intolerant of acidity and grow on neutral or calcareous soils (Wherry, 1942). The former are frequently referred to as calcifugous and the latter as calcicolous plants. Other species are essentially indifferent to soil reaction. A chemical study, with special reference to the aluminum, iron, manganese, phosphorus, calcium, and potassium content, of several species which grow on soils of contrasted pH values has been undertaken. It was hoped to obtain in this way a possible explanation as to why individual species thrive only on soils with a limited range of reaction.
