Korthalsia is a clustering genus of flowering plant in the palm family Arecaceae spread throughout Southeast Asia. It is a highly specialized rattan with some species known to have an intimate relationship with ants, hence the common name ant rattan. High-climbing and armed with spines, the genus is named for the Dutch botanist Pieter Willem Korthals who first collected them in Indonesia.

==Description== In young plants the trunks, petioles and rachises are covered in spines. Mature plants typically lose rachis and petiole spines but will retain trunks spines in its new growth. The suckering stems are small to mostly moderate and are among the few in the palm family that branch; among rattans it is the only one with splitting stems. These splits are axil branching, and produce "vast aerial entanglements" The trunks are bare at the bottom but retain persistent leaf bases in its youngest parts; enlarged paper-like appendages, ocreas, form where the petioles meet the stem. The ocreas are usually grossly swollen and house ants. Younger leaves are undivided with the occasional bifid apice. A truly pinnate leaf form comes in maturity and is accompanied by a barbed rachis extension which allows the palm to hook onto forest vegetation and climb to the canopy top where mature pinnae hang pendent. Also unique to the group are the rachis borne stalks, adapted for climbing, from which the leaflets emerge.
