M. beccarii is distinguishable from other ant plants through its small and succulent leaves, as well as through its tendency to develop multiple stems. Typical for most ant plants are the hypocotyls, which are stems that enlarge to form a tuber-like structure. In Myrmecodia beccarii, these hypocotyls are covered in ridges and spines. The white flowers are not very conspicuous, as they are formed in hollows along the alveoli (stem). The ripe fruit then protrudes from the alveoli and they can be white, red, orange or pink.
