Description and Ethnobotany

Growth Form Rhizomatous fern to 2m tall; unmistakable due to the unequally lobed, fan-shaped leaves,.
Foliage Fronds mid green, laminae to 70cm wide by 50cm long, divided nearly to the base into two fan shaped lobes, each half again divided into four unequal lobes more than halfway to the base, these lobes again divided unequally. Juvenile fronds tomentose (with a layer of downy hairs). Sori small and numerous, scattered irregularly on under surface of the fertile frond. 
Habitat In other parts of its range, this species usually found in forest clearings at mid to high altitudes (300m - 1,500m asl), often forming dense stands where growing conditions are ideal.  In Singapore, this species can be found at sea level, but has only been recorded from coastal cliffs/forests thus far, and has a very restricted distribution (Currently at Western catchment & several offshore islands; a population previously recorded from an undisturbed area in the Labrador nature reserve no longer persists, for unknown reasons.)
Ethnobotanical Uses Medicinal ( In Fiji, this species is known as  'Koukoutagane' and is used to treat male reproductive ailments. The rhizomes  are also gathered for folk medicine in Southern Thailand. )
