Flaveria bidentis, the coastal plain yellowtops, is a South American plant species of Flaveria within the family Asteraceae. It is native to South America, and naturalized in many places (Mexico, Central America, the West Indies, the southeastern United States, Europe, Africa, Asia, etc.).Cabrera, A. L. 1978.

Coastal plain yellowtopsFlora of China, Flaveria bidentis (Linnaeus) Kuntze, 1898. 黄顶菊 huang ding ju In the U.S. it is native to Georgia, Alabama and Florida. Flaveria bidentis is an annual herb up to 100 cm tall. One plant can sometimes produce 100 or more flower heads in a tightly packed array. Each head contains 3-8 yellow disc flowers. Sometimes the head also contains a single yellow ray flower.Powell, Albert Michael. 1979.

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 Flaveria bidentis has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Flaveria bidentis 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
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.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

Where the DNA of Flaveria bidentis 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.
