Dicranopteris linearis is a common species of fern known by many common names, including Old World forked fern, uluhe (Hawaiian), and dilim (Filipino). It is one of the most widely distributed ferns of the wet Old World tropics and adjacent regions, including Polynesia and the Pacific.[3] In parts of the New World tropics its niche is filled by its relative, Dicranopteris pectinatus.[3]
This rhizomatous fern spreads via cloning, spreading along the ground and climbing on other vegetation, often forming thickets 3 metres deep or more. The stem grows from the rhizome, branches at a 45° angle, and forms fronds that continue to bud and branch. In this way the growth can continue for a long distance as the plant forms a mat, grows over itself in layers, and spreads.[4] When climbing, the leafy branches can reach over 6 metres long[5] and can climb 10 high when supported by a tree.[3] The ultimate segments of the leaves are linear in shape, up to 7 centimeters long by a few millimeters wide. The undersides are hairy and sometimes waxy.[6] It can also reproduce via spores.[4]
The fern grows easily on poorly drained, nutrient-poor soils and in disturbed habitats and steep slopes.[3][4] It does not tolerate shade, so once established it will eventually be shaded out by taller vegetation unless it climbs above it.[3] It may suppress the growth of new stands of trees, especially when it becomes a dense thicket.[3]

The Diliman district in Quezon City in the Philippines' National Capital Region derived its name from Dicranopteris linearis, locally known as "Dilim" (the suffix "-an" indicates a place where something, in this case the fern, is common). As such, it is also the origin of the name of the University of the Philippines Diliman campus.[9]
