Apodytes dimidiata (white pear or umDakane) is a bushy tree with white flowers bearing a fragrance reminiscent of fresh coconut, and small black and red fruits. It is usually about 5 m tall (but reaches a height of 20 m when growing in deep forest), and it is indigenous to Southern Africa. The taxonomical family placement for this and other Apodytes was uncertain; it is now placed in the Metteniusaceae. Its English common name is in reference to the timber which is similar in appearance to that of the European pear tree of the northern hemisphere.

Compounds documented for Apodytes dimidiata 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 Apodytes dimidiata has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualApodytes dimidiata 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.

Where the DNA of Apodytes dimidiata 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.
