'agrostographical' originates from Greek, specifically the word 'agrostographia,' where 'agrostis' meant 'grass' and 'graphia' meant 'writing or description.'

'agrostographia' transformed into the English word 'agrostography,' and eventually became the modern English adjective 'agrostographical.'

Initially, it meant 'writing about grasses,' but over time it evolved into its current meaning of 'relating to the description or classification of grasses.'
