pleustophyte - Weblio 英和・和英辞典 (original) (raw)

The planktophytes and smaller pleustophytes (i.e. the Lemnids and Ricciellids in the sense of DEN HARTOG & SEGAL 1964) differ from all other water plants by forming mobile synusiae, able to shift from one phytocoenose to another.
Before going into detail it is useful to distinguish with LUTHER (1949) between haptophytes (adnate or non-rooting hydrophytes), rhizophytes (radicant or rooted hydrophytes), planktophytes, and pleustophytes (i.e. microscopic and macroscopic errant or mobile hydrophytes respectively).
