Stachyurus chinensis (中国旌节花), Chinese stachyurus, is a species of flowering plant in the family Stachyuraceae, native to China and Taiwan. It is a spreading deciduous shrub growing to 2.5 m tall by 4 m wide. Stiff, pendent racemes of bell-shaped, greenish-yellow flowers are borne on glossy, dark brown branches in winter and spring. It flowers two weeks later than the related S. praecox. The flowers are followed by simple ovate leaves which colour to pink and red before falling in autumn. The Latin specific epithet chinensis means "from China". This is the most widely distributed species of the genus, and is found throughout southern and eastern China as well as the island of Taiwan. It is also highly variable, with some populations on the mainland more closely resembling S. himalaicus. The two species may be better regarded as conspecific. This plant is cultivated as an ornamental subject in temperate parks and gardens. Although hardy, it prefers a sheltered location, and is suitable for training against a wall. It needs an acid or neutral soil. Two cultivars have gained the Royal Horticultural Society’s Award of Garden Merit: ’Celina’ (flower racemes longer than the species) ’Joy Forever’ (leaves spotted and flecked with yellow)

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

06Genome at a glanceCCDB
The complete instruction manualStachyurus 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.

Where the DNA of Stachyurus 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 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.
