'seed-leaved' originates from the combination of 'seed' and 'leaf', where 'seed' refers to the reproductive part of a plant and 'leaf' refers to the organ of a plant that is typically green and flat.

The term 'seed-leaved' has remained relatively unchanged in its usage, consistently referring to plants with leaves that develop from seeds.

Initially, it meant 'having leaves that develop from a seed', and this meaning has largely remained the same in modern usage.
