Gametophytes of seven species of ferns raised from spores on agar medium, are described. These are either cordate (Cheilanthes, Hypodematium, Cyclosorus and Tectaria) or lobed, thalloid (Actiniopteris, Asplenium and' Adiantum). All are homosporous ferns but in some of the taxa distinction is observed between antheridia and archegonia bearing prothalli (Cheilanthes, Hypodematium and Tectaria). Variations in morphology, sex expression and sporophyte formation are discussed.

Abstract


Gametophytes of seven species of ferns raised from spores on agar medium, are described. These are either cordate (Cheilanthes, Hypodematium, Cyclosorus and Tectaria) or lobed, thalloid (Actiniopteris, Asplenium and' Adiantum). All are homosporous ferns but in some of the taxa distinction is observed between antheridia and archegonia bearing prothalli (Cheilanthes, Hypodematium and Tectaria). Variations in morphology, sex expression and sporophyte formation are discussed.
