Phlegmariurus squarrosus (G.Forst.) A.Love & D.Love occurs throughout Oceania but is usually restricted to wet lowland rainforest gorges where it grows on boulders and trees near creeks and waterfalls. It was first named from Tahiti from material collected by the Forster’s on James Cook’s second exploration. In Australia it is restricted to the wettest gorges in a small area and has been significantly depleted in the past by plant-collectors.
