Pectis papposa is a species of flowering plant in the family Asteraceae. It is native to North America, where it occurs in the southwestern United States as far east as Texas, and in northern Mexico. Common names include cinchweed,Floristic Diversity and Discovery in the California Desert, James M. Andre, Fremontia, VOl. 42, No.1, January 2104, p.6 photo caption common chinchweed, many-bristle chinchweed, and many-bristle fetid-marigold.Pectis papposa. NatureServe. 2012. This is a host plant of the beet leafhopper.Kearny T. H., et al. Arizona Flora. University of California Press, Berkeley, CA. 1960.

05DNA & barcoding7 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 Pectis papposa has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPectis papposa 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.

Where the DNA of Pectis papposa 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.
