It is a distinct fan palm, with a bare petiole which extends as a center spine or midrib, 1/2 to 2/3 the length into a rounded, costapalmate fan of numerous leaflets.A costapalmate leaf has a definite costa unlike the typical palmate or fan leaf, but the leaflets are arranged radially like in a palmate leaf.

The flowers are yellowish-white, .20 in across, produced in large compound panicles up to 8.2 ft long, extending out beyond the leaves. The fruit is a black drupe about .5 in long containing a single seed. It is extremely salt-tolerant and is often seen growing near both the Atlantic Ocean coast and the Gulf of Mexico coast.
