Pouched Coral Fern

G. dicarpa consists of numerous fronds arising more or less vertically from a thin many branched rhizome. Each frond can reach 2 m (7 ft) in length with pinnae up to 4 cm (1.6 in) long. The smallest end-branches, known as pinnules, are a mere 1 to 1.5 mm long and recurved margins that give them a cup- or pouch shape. In fertile fronds, two spores lie within the pouch. It is these pouches which give the fern its common name. The spores are yellowish and darken to black when ripe. Fronds growing in sunnier areas often have a bleached yellow coloration.

G. dicarpa is found throughout eastern Australia, from Queensland through New South Wales and Victoria and in Tasmania. It is widespread in Tasmania, where it is found up to altitudes of 900 m (3000 ft). It is widely distributed in New Zealand, where it is found on North, South and Stewart Islands, as well as the Chatham Islands. It is also found in New Caledonia. A common plant, often seen growing under waterfalls, in peatlands, under cliffs and in tall open forest. It can grow in nutrient poor conditions, preferring high humidity and good levels of sunshine and moisture. Its tangled roots collect detritus and prevent erosion. It can also be a pioneer species of disturbed ground.

Although not commercially available, G. dicarpa can be readily propagated from spores, and grows as long as it is not allowed to dry out and is not otherwise disturbed. It prefers acidic soil and sunny aspect.
