La Psycotre nerveuse est un arbuste de la famille des Rubiaceae originaire de la Jamaïque et de la Floride. Ses feuilles sont persistantes, grandes, simples et ovales ; ses fleurs blanches sont groupées en panicules. Appelées wild coffee en anglais, ses graines ne peuvent cependant pas être utilisées pour faire des boissons.

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 Psychotria nervosa has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPsychotria nervosa 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 Psychotria nervosa 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.
