Areca vestiaria - Trunks. January 2020. Location CAS Xishuangbanna Tropical Plant Garden, Mengla, Yunnan, SW China.
Areca vestiaria (pinang yaki or pinang merah) is a species of palm native to the rainforests of eastern Indonesia[1] especially North Sulawesi.[2] Its morphology is more diverse than other species of palms, and in particular the color of its upper trunk / crownshaft changes depending on altitude (varying between red and orange).[1]
The people of Sulawesi, near Bogani Nani Wartabone National Park, have long used the fruit of this palm as a male contraceptive.[3] They drink a decoction of the fruit flesh boiled in water.[3] The chemical composition of the fruit has been investigated with this in mind,[3] but this does not represent evidence of its effectiveness as an antifertility agent.
