ABSTRACT This study examined the life cycle of Polystichum ordinatum (Kunze) Liebm. Specimens were collected at Cuetzalan, Puebla, Mexico. The spores were sown according to the technique of Montoya-Casimiro et al. (2000). The germination pattern was of the Vittaria type, and prothallial development was of the Aspidium type. Two types of gametophyte were found: cordate with only archegonia and elongated with antheridia. In the latter type of gametophyte antheridia developed in four different positions: a) in the middle part, b) in a proximal central position, c) over the whole surface and, d) along the margin of the gametophyte. Trichomes were observed in cordate and elongated gametophytes; only gametophytes with marginal antheridia were gla...
