Floccus

Floccus is a Latin noun meaning tuft or lock of wool. In English scientific usage, the term is primarily descriptive rather than a formal taxonomic category; it appears mainly as a root in compounds or in historical descriptions to indicate a tufted or woolly appearance. The related root flocc- gives rise to several common descriptive terms such as floccose and flocculent, which describe tufted, fluffy, or wooly textures.

In botany, floccus is used descriptively to indicate plant parts bearing tufts of short hairs or trichomes. Such tufted structures can occur on leaves, stems, seeds, or reproductive surfaces, contributing to texture, protection, or dispersal traits. The term is more likely to be encountered as part of a longer descriptive phrase than as a standalone designation.

In mycology and other fields, the related descriptors floccose or flocculent are more frequently used to describe fluffy, tufted, or downy fungal colonies or surface textures. The noun floccus itself is not a common primary term in modern taxonomic keys or species descriptions, though historical literature may employ it to convey a tuft-like morphology.

In anatomy, similar concepts are conveyed by separate terms such as flocculus, a distinct brain structure; floccus and flocculus share a common Latin root but refer to different anatomical or morphological concepts in contemporary usage.
