  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Epiphytic fern, relatively large, up to 1 m tall by 1.2 m wide, with rosette-like foliage arrangement that acts to collect fallen detritus. Dark brown, creeping horizontally just below substrate surface, with short internodes (1 - 2cm), and fronds arising from multiple nodes.
      Foliage: Fronds light green, strap-shaped, 55 - 65 cm long by 8 - 14 cm wide, fairly thick and waxy with undulating margins, abaxially-protruding midrib and prominently-netted dark green venation, which becomes more conspicuous as plant ages. Conxex bulges in between primary and secondary veins result in fronds' dimpled reptilian appearance. Fertile and sterile fronds similar in form.
      Reproductive Parts (non-flowering plant): Spore cases round, numerous and densely scattered all across underside of frond in between veins, maturing from cream to brownish.
      Similar :
      Patented cultivar, originally derived from a naturally-occurring whole-plant mutation of a selection of Microsorum musifolium belonging to a private grower in Kuranda, Australia. Differentiated from the parent species by its bushier habit, smaller but more numerous fronds, smaller rhizomes and more rapid growth.
      Cultivation :
      One of the more hardy, easy-to-grown ferns. Prefers bright shade, exposure to more light promotes a more upright growth habit with shorter stiffer fronds. Likes good air circulation and high humidity, container-grown plants can be placed on top of a water-filled pebble tray, or over pond or water feature. Requires moist but porous and well-drained substrates, suitable potting mixes include coarse peatmoss, sphagnum moss, pine bark, cocopeat, compost and coarse sand. If grown indoors where plant cannot collect detritus, feed with weak fertilizer every other week.
      Etymology :
      Genus epithet 'Microsorum' means 'small sori', describing the spore cases on the underside of fronds. Species epithet 'musifolium' means 'banana-like leaves', a reference to the fern's elongated strap-like fronds. Note:- Genus epithet sometimes misspelt as Microsorium - an orthographic variant of the originally-published (1833) and accepted 'Microsorum'; the variant came about after botanist and name-originator Link inadvertently used both spellings in his subsequent 1841 publication.
      Ethnobotanical Uses :
      [Others]: Freshly-cut fronds used as an attractive accent in floral arrangements.
