Pentanema salicinum (common name Irish fleabane (UK) or willowleaf yellowhead) is a plant species in the family Asteraceae. It is found across Eurasia from Portugal to Japan. It has been reported growing in the wild in a few scattered locations in North America but it has not become widely established there.Altervista Flora Italiana, Inula salicina L.Flora of North America, Inula salicina Linnaeus, 1753.Flora of China, Inula salicina Linnaeus, 1753. 柳叶旋覆花 liu ye xuan fu hua

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 Pentanema salicinum has left across the world's sequence archives.
At a glance
The complete instruction manual Pentanema salicinum 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.

Range
Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.
Museum / Voucheredphysical evidence
Backed by a physical specimen — a herbarium sheet, sample or voucher held in a collection. “Vouchered” means supported by material evidence, not just an observation.

Where the DNA of Pentanema salicinum 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.
