Flaveria linearis, known as narrowleaf yellowtops, is a North American plant species of Flaveria within the family Asteraceae. It is native to Florida, Cuba, Bahamas, and the Yucatán Peninsula of Mexico.Biota of North America Program 2014 county distribution map Flaveria linearis is a perennial herb up to 80 cm tall. Leaves are long and narrow, up to 13 cm long. One plant can produce sometimes as many as 150 small flower heads in a branching array. Each head contains 2-8 yellow disc flowers and sometimes a single yellow ray flower.Flora of North America, Flaveria linearis Lagasca, 1816. Narrowleaf yellowtopsPowell, Albert Michael. 1979. Annals of the Missouri Botanical Garden 65(2): 615-618 description and commentary in English, distribution map on page 616

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 linearis has left across the world's sequence archives.

The complete instruction manualFlaveria linearis 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 size≈1 654 553 644 bp assembly estimate
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.

09Environmental DNA3 detections
Where the DNA of Flaveria linearis 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 strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
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.
