Beccariophoenix is placed in the
subfamily Arecoideae and the tribe
Cocoseae. The species was first noted in 2002, when Alfred Razafindratsira noticed a picture of a
Beccariophoenix species in photographs taken of the vegetation surrounding
Andrembesoa (originally taken in search of a species of
Pachypodium in the rocky escarpments to the southwest of
Antsirabe). Alfred found this odd, considering this area of Madagascar is far from the other localities of
Beccariophoenix and is, furthermore, ecologically totally different from the east coast and littoral forests where the other
Beccariophoenix species are known to occur. On a day in May 2004 an expedition was mounted into the High Plateau of Madagascar in order to confirm the existence of this species. On the fourth day of the expedition the new population of
Beccariophoenix was found. This species is noted for having oblate (flattened spheroid) rather than ovoid fruit, infrafoliar inflorescence (rather than interfoliar), a
peduncle not exceeding long (rather than one up to long), a thick leathery peduncular
bract which rolls up on when itself when abscised (rather than a heavily lignified peduncular bract thick, which does not deform when abscised) and 15
stamens (rather than 18–21). Due to these differences,
Beccariophoenix alfredii was classified as a new species. ==Habitat and distribution==
