the word 'zoysia' is an eponym, a scientific name derived from that of a person. it was coined in the 18th century by the austrian botanist carl von linné (linnaeus) to honor his colleague, the german botanist karl von zois. the genus name 'zoysia' was formed by latinizing the surname 'zois' and adding the typical botanical suffix '-ia'. this practice of naming plant genera after fellow scientists was common in linnaean taxonomy. thus, the term carries no inherent descriptive meaning about the plant's characteristics but functions purely as a taxonomic label honoring an individual.

this is a simplex word. it is a modern latin genus name, derived from a personal name.
