A genus of palms which grow solitarily or in small clumps. The leaves are pinnate with a conspicuous crown-shaft. Inflorescences occur distally with only male flowers, and near the base triads a big female is flanked by 2 males. The fruits have a fleshy mesocarp (see pericarp). The betel-nut comes from A. catechu. There are about 50 species, native to tropical Asia and the western Pacific.
