1983 R. G. Wetzel Limnology (ed. 2) viii. 138 A group of algae found aggregated in the lottoral zone is the metaphyton,..which is neither strictly attached to substrata nor truly suspended.

1997 Hydrobiologia 362 188/1 We categorized periphyton in three types: (1) floating mats (metaphyton), which were either free-floating or associated with floating macrophytes.
