'elevated-stemmed' originates from the combination of 'elevated,' meaning 'raised or lifted,' and 'stemmed,' referring to the stalk or main axis of a plant.

'Elevated' comes from the Latin word 'elevatus,' meaning 'raised,' and 'stemmed' is derived from the Old English 'stemn,' meaning 'stalk.'

Initially, it meant 'having a raised stalk,' and this meaning has largely remained the same in modern usage.
