01Narrative

Desmos chinensis growing as a shade tree in Bangkok; note the blue metal support Desmos chinensis is a flowering plant of the custard-apple family, Annonaceae. The yellowish-green flowers are similar to the Ylang-ylang flowers, therefore this plant is sometimes known as dwarf ylang-ylang.Desmos chinensis; Dwarf Ylang Ylang Shrub Their smell, however, is much less strong and is only felt in the morning. By midday it has mostly faded away.

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 Desmos chinensis has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Desmos chinensis 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.

09Environmental DNA9 detections

Where the DNA of Desmos chinensis 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.
