A palm 10–20 m tall with a single straight trunk ringed by leaf scars and no branching. Very long pinnate fronds cluster at the crown. Unisexual flowers form spikes; the ovoid fruit is 4–6 cm long, green turning orange-yellow, and holds a single reddish-brown, mottled seed (areca nut).
Areca nut contains arecoline, which is mildly stimulating and stains red when chewed; the betel custom is tied to Vietnamese wedding and ceremonial culture. Health caution: habitual betel-quid chewing (especially with tobacco) raises the risk of oral cancer and should be limited.
