Phillips 1989, p. 452; Tanner 1979, p. 78; Setchell and Gardner 1920 b, p. 271 Life History: alternation of isomorphic phases, with the sporophyte producing quadriflagellate zoospores and unisexual gametophytes producing biflagellate anisogametes; male and female gametes capable of parthenogenetic development mostly of gametophytes, less commonly of sporophytes ( J. Phillips 1990; Smith 1947 ) Biology/Ecology: R. Lee 1965 b, p. 118
