Etymology/Origin
The generic name Alpinia honors the Italian physician and botanist Prospero Alpini (1553–1617), who documented numerous tropical plants. The specific epithet rafflesiana commemorates Sir Thomas Stamford Raffles (1781–1826), the British statesman noted for founding modern Singapore and for his contributions to natural history in the region.
