Myrmecodia beccarii, ant-house plant, is an epiphytic plant on Melaleuca trees and others with spongy bark in the wetlands and mangroves of tropical north Queensland, Australia from Cooktown to Mission Beach. The prickly, swollen caudex develops natural hollows which are colonised by the golden ant (Philidris cordatus) in a symbiotic arrangement. The ants patrol the plant, removing leaf-eaters, while their excreta is absorbed by the plant for nutrition. The flowers are white and tubular, to 10 mm, and the fruit is white/translucent containing a single seed. These seeds are transported to other trees by the mistletoebird (Dicaeum hirundinaceum).
