Chamaecrista fasciculata, the partridge pea, is a species of legume native to most of the eastern United States. It is an annual which grows to approximately 0.5 meters tall. It has bright yellow flowers from early summer until first frost, with flowers through the entire flowering season if rainfall is sufficient. The flowers are hermaphroditic, although a fraction of plants, less than 5%, do not produce sufficient pollen to reproduce as males. This phenomenon has been studied in a variety of plants as a possible evolutionary step towards dioecy, in which male and female flowers occur on separate plants. C. fasciculata is pollinated only by bees. The flowers have yellow anthers that produce reproductive pollen, and purple anthers that produce food pollen, but no nectar. Long-tongued bees such as bumblebees, honey bees, long-horned bees, and leafcutting bees pollinate the flowers. There are extrafloral nectaries on the leaf stems, which attract a different set of insects: sweat bees, flies, wasps, and ants. It thrives in areas that have been burned recently before declining in number in the following years. It is considered an excellent choice for planting in disturbed areas, as it will quickly cover an area, preventing erosion, while still allowing other plants to become established. It is also grown as an ornamental or for honey production.

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 Chamaecrista fasciculata has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Chamaecrista fasciculata 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
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.

Where the DNA of Chamaecrista fasciculata 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.
Signal
Where its DNA was found
How strong is each trace?
Modelled climatemodelled
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.
