At present (April 2014) there are two recognized species. The first and better known is the Manila Palm (Adonidia merrillii). It is native to Palawan, Danjugan and Sabah, and reportedly naturalized in the West Indies. It is commonly known as the "Christmas Palm" because its fruits become bright scarlet and tend to be that color in winter. This palm is typically fairly small and slender, normally attaining 15–25 feet in height but has attained 36 feet grown in greenhouse conditions.
Some palms sold in retail outlets as "adonidia" are in fact Alexander palms, which are similar but even thinner.
Adonidia merrillii is widely planted in cultivation and grows well in tropical locations such as Hawaii and the southern half of the Florida peninsula. Its fruits are sometimes said to be used as a substitute for the betel nut, in preparing buyo (fruit of Areca catechu, leaves of Piper betle, and lime) for chewing.
