Shaped like an acinaces or curved sword; having a crescent or scimitar-like form.
From 'acinaces' (curved sword) plus Latin '-form' (shaped like). This botanical term evolved to describe any curved, pointed object that resembles the historical Persian weapon.
Many leaves and fruits evolved curved shapes independently for survival advantages—this word lets botanists describe these shapes without knowing their function, making it useful across completely different plants!
