Catalpa ovata, the yellow catalpa or Chinese catalpa (), is a pod-bearing tree native to China. Compared to C. speciosa, it is much smaller, typically reaching heights between 20 and. The inflorescences form 4 - bunches of creamy white flowers with distinctly yellow tinging; individual flowers are about 1 in wide. They bloom in July and August. The leaves are very similar in shape to those of Paulownia tomentosa, having three lobes (two are abruptly truncated on either edge, with a third, central, slightly acute, pointed lobe forming the leaf apex), and are darkly green. Fruits are very narrow, foot-long pods. Although native to the more temperate provinces within China (Anhui, Gansu, Hebei, Heilongjiang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Monggol, Ningxia, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, Xinjiang), C. ovata is also cultivated in North America and Europe, and has become a parent of Catalpa × erubescens with the American species Catalpa bignonioides. It is commonly used to make the undersides of qin.

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 Catalpa ovata 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 Catalpa ovata 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.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Catalpa ovata 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.
