betel nut palm, areca, areca-nut; pugua (Guam), poc (Pohnpei), pu (Truk), bu (Yap), bua (Palau), buai (New Ireland: Kuanua), buei (New Ireland: Pala), vua (New Ireland: Lamekot). Several of the common names in the Pacific are derived from the pidgin buai.
Prefers hot, humid tropical with uniform rainfall, elevations 0 - 900 m.
Betel nut palm is native to East Africa, Madagascar, Arabian Peninsula, India, Sri Lanka, Bangladesh, Myanmar, Thailand, Cambodia, Laos, Vietnam, southern China, Malaysia, Indonesia, Philippines, Papua New Guinea, Fiji, Micronesia (Guam, Palau, Pohnpei, Truk, Yap), Vanuatu. Dispersal by humans to other areas of the Pacific and elsewhere has played a role in the naturalization of the species outside its range.
This species is widely introduced throughout other tropical regions of the world where it may be invasive in some areas and invasiveness outside its naturally occurring range is unknown.

Seedlings have reached target size when they have 5 - 7 leaves and are about 20 - 30 cm tall.
Ripe fruits are available year-round. Collecting freshly fallen fruits from the ground is the most practical method. Betel nut palms are only known to be found in cultivation.
Fresh seeds should be used, which usually have a high germination of about 90%.
Removal of the outer husk is not necessary to achieve good results. Air drying the seeds for 1-2 days in the sun or 3 - 7 days in the shade is done, though not necessary.
Seedlings are grown in partial shade. Hot, humid conditions speed germination and growth.
Seeds are pregerminated in beds. Prepare beds of loose, organically rich potting medium, such as a 1:1 mix of peat moss and perlite or vermiculite. Lay the betel nut seeds on their sides and bury about 2/3 of the way, leaving one third above the potting medium. A loose mulch of finely sifted black cinder or granite chips can be used to help conserve moisture and protect the medium from driving rain if exposed to the elements. Germination takes about 3 months. Bottom heat will help speed germination. Late germinating or weak seedlings should be discarded, as these tend to produce less vigorous plants.
4 months
Transplant germinants to individual containers after the leaves begin to appear. One gallon root training containers are suitable. Amending monthly with additional fertilizer such as a light top dressing of Gro-More 8-8-8 will aid in growth and development. Weeds should be prevented from entering the growth area to avoid competition for light an nutrients.
8 months
If the seedlings are not already growing in full sun, move them into a sunny area, spacing seedlings out further if necessary. Seedlings should never be allowed to dry out, but watering frequency may be reduced to introduce seedlings to temporary, moderate water stress.
1 month
When the plants have reached target size, they may be delivered to the planting site. They are not extracted from their container or stored before shipping. Keeping plants in their container is necessary to protect the roots.
Although betel nut has important cultural uses throughout the Pacific, heavy use is associated with serious diseases particularly of the mouth.
