Characteristics

A small clumpy palm with several stems. The palm is 8 m tall and the stems are 10 cm across. It has leaves which are once branched (uni-pinnate) and with narrow, long, leaflets along the leaf stalk. The leaflets form a V shape along the midrib. The leaflet at the end is often triangular. The leaf fronds arch over. The flower stalk is like fishtail palm but smaller. This stalk is produced from among the leaves. The flower stalk is large and with simple branching. The highest flowers are female and the lower ones can be male or of both sexes. The fruit spikes hang over and are densely clustered with fruit. The fruit are red and juicy. They are 1.5 cm across. There are 2-3 seeds inside a fruit.
