'equisetifolia' originates from Latin, specifically the word 'equisetum,' where 'equi-' meant 'horse' and 'setum' meant 'bristle,' combined with 'folia' meaning 'leaves.'

'equisetum' transformed into the modern scientific name 'equisetifolia' to describe the plant's bristle-like leaves.

Initially, it referred to plants with bristle-like leaves, and this meaning has largely remained the same in modern usage.
