01Narrative
Commelina diffusa, appelée « Petite-Herbe-de-l'eau » à La Réunion, est une espèce de plantes monocotylédones de la famille des Commelinaceae. Cette plante herbacée annuelle originaire des régions tropicales est une importante mauvaise herbe dans de nombreuses cultures, notamment aux États-Unis et en Amérique centrale. C'est dans une population de cette espèce que fut signalé l'un des premiers cas de résistance aux herbicides en 1957 à Hawaï.

05DNA & barcoding13 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 Commelina diffusa has left across the world's sequence archives.

06Genome at a glanceCCDB · GIFT · GoaT
The complete instruction manual Commelina diffusa 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 size5 770 200 000 bp
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. Click any value below to see the underlying records and sources.

A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
09Environmental DNA8 detections
Where the DNA of Commelina diffusa 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.
