Photo courtesy of Patrick Dalton.Hymenophyllum peltatum (hymen-o-FIL-lum, pel-TAH-tum), is a species of filmy fern widely distributed across Australia, New Zealand, South Africa, South America.[1][2][3][4] Predominantly a rainforest species with delicate foliage arrangements, also known as the ‘alpine filmy-fern‘. Members of the Hymenophyllaceae family display almost translucent fronds, bearing thickness of just a single cell.[3][4][5][6][7]Table of ContentsDescription[edit]Habitat and distribution[edit]Nomenclature[edit]Conservation values[edit]Affinities[edit]References[edit]Description[edit]Rhizome: The glabrescent (near hairless) rhizome forms a creeping, interlacing thread across various substrates, including larger ferns such as Dicksonia antarctica, rocks and fallen logs.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Leaves: Each frond consists of several dark-green pinnae encompassing multiple lamina, with toothed margins and a single vein.[3] Size can vary from 1.5 \u2013 17cm in length. H. peltatum is distinguished from otherwise similar relatives (such as H. cupressiforme) by the unique \u2018apically winged\u2019 foliage,[4] where branching only occurs on the apex side (i.e. toward the main stem), known as acroscopic branching.[4]Sori occur (1-2) on the acroscopic side of the primary pinna. When mature, each sorus is attached by a small, peltate branch, hence the name H. peltatum.[5] The sorus is a funnel-shaped receptacle, housing numerous sporangia, each approximately 1-2mm long and 0.5-1mm wide.[4] The indusium forms a cleft of two-lips, which have entire margins protecting the developing sporangia.[4]Habitat and distribution[edit]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.[3] One of 19 Hymenophyllum species found in Australia, H. peltatum can be observed across Tasmanian alpine regions, Victoria, NSW, and rarely in Queensland.[3][4] Habitat includes wet, mossy banks, rocks and logs. It also occurs as an epiphyte on trees such as Nothofagus cunninghami and Atherosperma moschatum.[6]Nomenclature[edit]Hymenophyllaceae: displaying the thinnest fronds of any fern species,[7]hymen is derived from the Greek word for ‘membrane’, and phyllon meaning ‘leaf’.[5] Another defining feature is the sorus structure, a two-flapped indusium which houses the sporangia in a protective receptacle, often clustered around a central axis.[5] Subgenus Hymenophyllum is defined by the toothed margins of each lamina within a frond.[5]Peltatum: When mature, each sori is attached by a small, ‘peltate’ branch, hence the name H. peltatum which is derived from the Latin word peltatus, used to describe an organ attached by a central stalk.[5]‘Alpine’ filmy fern: This particular species is generally observed 600m above sea level.Conservation values[edit]Warming temperatures, increased fire events and changes in land use could see reduced habitat potential for H.peltatum.Affinities[edit]Easily confused with H. cupressiforme, which has slightly larger fronds and pinnae are branched on both sides.[4]References[edit]^ “Checklist of Ferns and Lycophytes of the World – Hymenophyllum peltatum (Poir.)
