01Narrative
Erechtites hieraciifolius (fireweed, American burnweed, or pilewort) is a plant in the daisy family, Asteraceae. It is native to the Americas, but is found many places around the world having been introduced by human activity. It is introduced in Hawaii, China, and Southeast Asia.United States Department of Agriculture Plants Profile for Erechtites hieraciifoliaFlora of China, 梁子菜 liang zi cai, Erechtites hieraciifolius (Linnaeus) Rafinesque ex Candolle

05DNA & barcoding31 specimens
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 Erechtites hieraciifolius has left across the world's sequence archives.

06Genome at a glanceCCDB · GIFT · GoaT
The complete instruction manual Erechtites hieraciifolius 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.
Genome sizehow big the whole instruction manual is
Genome size5 452 350 000 bp
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).

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.

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.
