Description and Ethnobotany
| Growth Form | It is a large, upright fern with creeping rhizomes which forms thickets, large dense bushes easily. |
|---|---|
| Foliage | The foliage branches out several times equally. The ultimate branch measures about 40 cm long, 12 cm wide, bears deeply lobed, pinnatifid leaflets. It has a greyish-blue underside, pinkish hairs may be found on the veins. |
| Reproductive Parts - non-flowering plant | The sori are round, produced on either sides of the midrib in a single line. |
| Others - Plant Morphology | The rhizomes are long-creeping, 3 - 5 mm in diameter, covered in dark brown stiff hairs. |
| Habitat | Occurs in thickets from sea level up to 1500m. <1,2> |
| Similar | Dicranopteris curranii and Dicranopteris linearisshow similarities. D. curranii is significantly larger than D. linearis in terms of its size and individual fronds. The former is strongly erect unlike D. linearis which tend to be limp. |
| Cultivation | It can be propagated through rhizomes and spores |
