'rigid-leaved' originates from the combination of 'rigid,' meaning 'stiff or unyielding,' and 'leaved,' referring to the leaves of a plant.

'Rigid' comes from the Latin word 'rigidus,' meaning 'stiff,' and 'leaved' is derived from the Old English 'lēaf,' meaning 'leaf.'

Initially, 'rigid' meant 'stiff or hard,' and 'leaved' referred to the foliage of plants. Together, they describe plants with stiff leaves.
