01Narrative

Amorphophallus yunnanensis (滇蘑芋, dian mo yu) is a flowering plant species native to forests and thickets, at altitudes of 100–3300 meters, in Guangxi, Guizhou, and Yunnan provinces in China, as well as Laos, and northern Thailand and Vietnam. Its tuber is dark brown, up to 13 cm in diameter, and weigh up to 500 grams. The leaf is solitary, 6–35 cm, grayish green, covered with pale pinkish spots. The inflorescence is solitary, 13–60 cm in height and 1–2 cm in diameter at its base. Berries are initially green, then turning blue and finally violet.

05DNA & barcoding2 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 Amorphophallus yunnanensis has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Amorphophallus yunnanensis 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.

09Environmental DNA2 detections

Where the DNA of Amorphophallus yunnanensis 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
