laminatoi

Laminatoi is a term that has appeared in some historical and obscure taxonomic writings to designate a proposed grouping of organisms characterized by laminated or layered structures in their tissues or cell coverings. The name derives from lamina, meaning plate or layer, and a suffix used in the formation of taxonomic names. It is not a formally recognized clade in modern systematics, and there is no single, universally accepted definition or circumscription.

In practice, usages of laminatoi have varied. Some authors applied the term to certain protists with layered cell walls or pellicles, while others extended it to macroalgae or other organisms with laminated tissues or extracellular matrices. Because of this variability, laminatoi has little standing in current taxonomy and is rarely represented in contemporary phylogenetic analyses or major databases such as NCBI or WoRMS.

Taxonomic status is therefore ambiguous; in many modern treatments, researchers prefer to describe organisms by established names and clades rather than employing the umbrella label laminatoi. When encountered, the term is typically treated as of historical interest rather than as a rigorously defined lineage.
