About
Hymenophyllum peltatum, also known as alpine filmy-fern, is a species of filmy fern widely distributed across Australia, New Zealand, South Africa, South America. It is predominantly a rainforest species with delicate foliage arrangements. Members of the Hymenophyllaceae family display almost translucent fronds, bearing thickness of just a single cell.
Where it grows
While not as common as H. cupressiforme species, H. peltatum is widespread and known to occur in cool temperate to sub-tropical rainforests around the world, including Australia, New Zealand, South Africa and South America. One of 19 Hymenophyllum species found in Australia, H. peltatum can be observed across Tasmanian alpine regions, Victoria, NSW, and rarely in Queensland. Habitat includes wet, mossy banks, rocks and logs. It also occurs as an epiphyte on trees such as Nothofagus cunninghami and Atherosperma moschatum.
