Calamus caryotoides, commonly known as fish-tail lawyer cane, is a climbing palm native to Queensland, Australia.

A small amount of soft pulp lies beneath, surrounding the single globose seed which measures about 8 mm (0.3 in) diameter.

In 1820 a fertile specimen was collected and eventually described by the English botanist and explorer Allan Cunningham, however his description was invalidly published, and so it wasn't until 1850 that a formal, valid description was published by the German botanist Carl Friedrich Philipp von Martius in volume three of his book Historia naturalis palmarum.

[7] The fish-tail lawyer cane is found from near the top of Cape York Peninsula, southwards along the coastal regions to about Mount Elliott near Townsville.

[5][9] The Cairns Botanical Gardens records that the Yidinydji, Yirrganyydji, Djabuganydji, and Gungganyji use this plant as follows: The thin flexible trunks of this (and other) climbing palm made ideal building frames, or rope and string when split.
