Callicarpa dichotoma, the purple beautyberry or early amethyst, is a species of beautyberry. They are cultivated as garden shrubs. The flowers are pink to white. The berries which are small drupes are purple. The fruits grow closely together in large clusters. The fruit provides food for wild life. The berries are edible and have a mild taste. This species can be found in China, Vietnam, Korea and Japan.

Compounds documented for Callicarpa dichotoma across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Callicarpa dichotoma has left across the world's sequence archives.

The complete instruction manualCallicarpa dichotoma 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. Click any value below to see the underlying records and sources.

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.
