Hymenophyllum peltatum. 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. 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.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Hymenophyllum peltatum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualHymenophyllum peltatum carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Where the DNA of Hymenophyllum peltatum was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
