01Narrative

Christella normalis, synonym Thelypteris kunthii, sometimes known as Kunth's maiden fern or southern shield fern, is the most common of the maiden ferns in the southeastern United States south of the fall line. It ranges westward to eastern Texas. It usually grows in moist to dry terrestrial situations, but can also be epipetric. It often grows as a greenhouse escape in areas north of its usual range.

05DNA & barcoding1 eDNA hits

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 Pelazoneuron kunthii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Pelazoneuron kunthii 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.

09Environmental DNA1 detections

Where the DNA of Pelazoneuron kunthii 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.
