| Sumario: | Spore germination and the development of the mature prothallia of Thelypteris rhachiflexuosa Riba follow the general pattern described elsewhere for other species of the genus; the germination is of Vittaria-type and the development of prothallia is of Drynaria-type. There is an early differentiation of short unicellular glandular hairs on margins and surfaces of the lamina. The opening of the antheridia is accomplished by separation of the whole cap cell. Archegonia have a neck with four rows of cells and in one archegonium five rows instead of four were seen. No sporophytes were observed after 100 days in culture. |
