'asperifolious' originates from New Latin, specifically the word 'asperifolius,' where 'asper-' (from Latin 'asper') meant 'rough' and 'folius' (from Latin 'folium') meant 'leaf'.

'asperifolious' changed from the New Latin botanical adjective 'asperifolius' (formed in scientific Latin from Latin roots) and was adopted into English as the adjective 'asperifolious' with the same descriptive botanical sense.

Initially it meant 'rough-leaved' in botanical Latin, and over time it has retained that specific meaning in modern English botanical usage.
