ABSTRACT
The development of the gametophytes of Thelypteris patens (Swartz) Small and Thelypteris puberula (Baker) Morton var. puberula is described in this paper. In both species the laminar, bidimensional stage follows a brief filamentous stage, which has a few cells. The adult prothallia are reniform or cordiform, with both marginal and superficial hairs. Gametangia are present 2-3 months after the sowing of the spores, and they are of the common type in advanced ferns. The significant differences between these species are size and abundance of hairs, shape of the adult prothallia, type of rhizoids, and the early development of the young sporophyte in Thelypteris patens.

    Although consensus has now been reached on a general two-locus DNA barcode for land plants, the selected combination of markers (rbcL + matK) is not applicable for ferns at the moment. Yet especially for ferns, DNA barcoding is potentially of great value since fern gametophytes—while...
