A small palm to about 2m (6 ft) with a branching, subterranean trunk. It has arched pinnate leaves, spineless, that are bright green above and silver below. The inflorescence comes from the middle of the plant, with cream or pale yellow flower clusters. The flowers often attract bees and beetles. It has small, orange fruit, that dries out quickly.
