Description and Ethnobotany
| Growth Form | It is a terrestrial fern that has adapted to fast-flowing waters (Rheophyte). |
|---|---|
| Foliage | The frond is pinnate, firm, up to 18 pairs of leaflets measuring 30 - 80 cm in length. The blade is held on a long stalk, 20 - 60 cm long. While the stalk remains glabrous and smooth, hooked hairs and rigid dark scales are found at the base. Leaflets grow between 10 - 15 cm long, fertile leaflets tend to be slightly narrow measuring 0.6 - 1.2 cm wide, rarely to 2 cm in width. A bud may be present at the base of the leaflet pair at the tip. |
| Reproductive Parts - non-flowering plant | The sori are elongated along the veins. |
| Others - Plant Morphology | The rhizomes are short-creeping, bearing sparse hooked hairs. |
| Habitat | Occurs on rocks, in and next to streams in forest, flood zone at 0 - 500 m altitude. <1> |
| Cultivation | It can be propagated by spores. |
| Etymology | The specific epithet 'salicifolia' refers to the appearance of the fronds, as they resemble Willow leaves (Salix spp.) |
