Uncommon, mid to large, solitary palm native to South Madagascar, where less than 200 specimens still live in the wild. It has a triangular crownshaft and it is actually reminiscent of a triangle palm, with greener and more plumose leaves. It is a "tillering" palm, so the base of the stem sinks in the ground during the first years of growth. Then it goes up.
It has some resistance to cold and it can grow outdoors in warm mediterranean climates.
