Cercis occidentalis, the western redbud or California redbud (syn. Cercis orbiculata — Greene), is a small tree or shrub in the legume family, Fabaceae. It is found across the American Southwest, from California to Utah and Arizona.USDA: Cercis orbiculata . accessed 3.23.2013 It is easily recognized when it is in bloom from March to May, when it is covered with small pink to purple flowers.

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 Cercis occidentalis has left across the world's sequence archives.

The complete instruction manualCercis occidentalis 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.

09Environmental DNA9 detections
Where the DNA of Cercis occidentalis 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.
