Etymology: The genus “Alpinia” is named in honour of Prospero Alpini (1553–1617), an Italian botanist and physician known for his pioneering studies on exotic plants, particularly those of Egypt. The specific epithet “purpurata” is derived from Latin, meaning “purple,” likely referring to the striking purplish-red bracts that are characteristic of this plant.
