Charpentiera

Charpentiera is a flowering plant genus in the pigweed family, Amaranthaceae. It consists of five species endemic to Hawaiʻi, where they are known as pāpala, and one species found only on the island of Tubuai in the Austral Islands. All species are trees, some reaching more than 10 metres (33 ft) in height. The genus is named for Arsène Charpentier (1781-1818), professor of pharmacy at Antwerp from 1810 to 1814 and at Cherbourg from 1814 to 1816. Native Hawaiians on the northwest coast of the island of Kauaʻi used lightweight pāpala branches in the art of ʻōahi. Branches were ignited and tossed off of high sea cliffs, where they were buoyed by ridge lifts and burned like fireworks.
