 Zombia antillarum is a small palm which grows in dense, multi-stemmed clumps with stems up to 3 metres (10 ft) tall and 5 centimetres (2 in) in diameter. Individuals bear nine to 12 fan-shaped (or palmate) leaves which are greyish-white on the lower surface. The leaf sheaths remain attached to the stem after the leaf drops off. The intervening tissue gradually degrades, and the woody vascular tissue splits, forming the spines which are characteristic of the species.
