Life History:
sexual reproduction not demonstrated in Pacific coast populations, plants recycling by means of aplanospores (Hanic 1979); in Europe, unisexual gametophytes producing biflagellate male gametes and non-flagellate female gametes; zygotic meiosis with genotypic sex determination; asexual reproduction not demonstrated (Kornmann and Sahling 1974). Note: Bravo (1962, 1965) interpreted the results of her culture studies as showing that Prasiola meridionalis and Rosenvingiella constricta are phases in the same life history. This equivocal matter was reviewed by Tanner (1981, pp. 220–222). Display references
