Abstract

The production of gametophytes from spores of the following species and hybrids of Hippochaete (Equisetaceae) taxa is reported: H. ramosissima (Desf.) Borner. H. x meridionalis (Milde) Holub (= H. ramosissima x H. variegata), and H. x moorei (Newm.) H.P. Fuchs (= H. hyemalis x H. ramosissima). The gametophytes were obtained from spores collected on plants occurring in two localities. Evolutionary consequences of the absence of complete hybrid sterility are discussed.
