Additional Information is given in this paper on morphogenetic features of the gametophyte of two fern species of the Blechnaceae. Woodwardia spinulosa, growing from the North of México to Central America (Nicaragua) has dark brown, bilateral and ellipsoidal spores with wavy and folded perispore; the germination pattern is of Vittaría type and the prothallial development is of Aspidium type. The mature gametophytes are bisexual, with antheridia and archegonia typical of leptosporangiate ferns. Juvenile sporophytes with one or two leaves were observed 11 months after spore germination. Woodwardia martinezii is only known from a few localities in the States of Veracruz and Hidalgo, México; the spores and the germination and prothallial...
