'angustifoliate' originates from New Latin, specifically the word 'angustifolius/angustifoliatus,' where 'angustus' meant 'narrow' and 'folium' meant 'leaf.'

'angustifoliate' changed from the New Latin botanical adjective 'angustifolius' used in taxonomic Latin and eventually became the modern English word 'angustifoliate'.

Initially, it meant 'narrow-leaved', and this meaning has largely remained the same in modern usage.
