Surface Forms

genus Chara singular

genera Chara plural

Morphology

genus + Chara

The phrase is directly compositional: 'genus' (a taxonomic rank grouping related species) combined with 'Chara' (the name of a green-algae genus) yields the meaning 'the taxonomic genus named Chara.' This is a formulaic, cross-linguistically common scientific construction, so a B1 learner who knows both constituents will readily understand the MWE.

Etymology

The name genus Chara combines genus, meaning a 'group' of similar kinds, with Chara, the name for a type of green algae. These algae look like small plants or underwater brushes that form thick meadows in lakes, so genus Chara refers to this particular group of freshwater algae.
