Appearance
Some specimens grow to a height of some 15 metres in the wild. The leaves are about 2.5 metres in length, growing almost upright from the trunk and arching gracefully outward about a metre from their tips. The leaf bases are arranged in three vertical columns set about 120 degrees apart on the main stem, forming a triangular shape in cross section. This shape has given rise to the palm's common name.The inflorescences branch out from the axils of the lower leaves. They produce yellow and green flowers that later produce round black fruit about 25 millimetres in diameter.
Status
Although this species is now commonly cultivated in a variety of climates, there are only about 1,000 individuals left in its native habitat of a small area in Andohahela National Park, southern Madagascar. It is threatened both by fire and the harvesting of its seeds for export.References:
