1978 H. C. Bold & M. J. Wynne Introd. to Algae 12 This type of life cycle was..said to be haplobiontic, meaning that only a single type of free-living individual is involved in the life cycle.

1991 Brit. Phycol. Jrnl. 26 303 Sargassum possesses a haplobiontic, diploid type of life history; the dominant morph is the sporophyte and there is no alternation of generations.
