  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: This fern plant consists of a rhizome (horizontally growing stem) that bears nest-leaves and repeatedly forked, ascending foliage leaves.
      Foliage: It produces two kinds of fronds. The infertile nest-fronds are corrugated, 20–50 by 20–40cm, and fold over one another to form an enclosed chamber with rounded base attached to host surface. The fertile fronds are 25–50 cm long or more, forked, stiff and leathery, grow upwards, resembling stag's antlers.
      Reproductive Parts (non-flowering plant):
      The lobes that bear the sporangia (spore-producing structures) are reverse egg-shaped to elliptic, and 5–17 by 3–15 cm. There are eight spores per sporangium.

      [Others]: It is the only species of Staghorn Fern with ascending fertile fronds.
      Associated Flora :
      It is often found in association with Lecanopteris species (Ant Ferns).
      Associated Fauna :
      Its nest-fronds are often colonized as nesting area by ants in the wild.
      Cultivation :
      Fern can be mounted onto tree branch/ trunk, or fern root slabs (which need daily misting).
      Etymology :
      Species named after British botanist and first director of Singapore Botanic Gardens from 1888 to 1911, Henry Nicholas Ridley, who discovered the plant in Bukit Timah forest (Singapore).
      Ethnobotanical Uses :
      None
