Artemisia arborescens, the tree wormwood, is a species of flowering plant in the family Asteraceae, native to the Mediterranean region.Altervista Flora Italiana, Assenzio arbustivo Artemisia arborescens (Vaill.) L. It is an erect evergreen perennial, with masses of finely-divided aromatic silvery-white leaves and single-sided sprays of yellow daisy-like flowers. This plant is cultivated for its foliage effects, but in colder temperate regions it requires the protection of a wall. The specific epithet arborescens means "woody" or "tree-like". This plant and the cultivar 'Powis Castle' have gained the Royal Horticultural Society's Award of Garden Merit. 'Powis Castle' is relatively compact, and unlike typical A. arborescens, it rarely flowers. It has a strong sweet smell, quite different from that of A. arborescens. It has been suggested to be a hybrid between A. arborescens and A. absinthium, but is probably a form from the Middle East where arborescems and absinthium appear to intergrade. The original source is unknown, but British gardener Jim Hancock took a cutting of a plant that he found growing during a garden visit in Yorkshire c1968, and took it to Powis Castle when he became Head Gardener there in 1972. It was later named from that garden, propagated and sold to promote the National Trust gardens.JD Twibell, Plant Identification from Vapour Analysis, The Plantsman 14 (3) 184-190 1992 This plant, like others of the genus Artemisia, yields essential oils which have historically been used for various medicinal purposes, and its pharmacological properties are under investigation. It also has culinary uses, including as a substitute for or supplement to spearmint in Maghrebi mint tea during the winter (when mint is out of season), imparting a bitter flavor.

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 Artemisia arborescens 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 Artemisia arborescens 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.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
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.

Origin
Range
Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.
Museum / Voucheredphysical evidence
Backed by a physical specimen — a herbarium sheet, sample or voucher held in a collection. “Vouchered” means supported by material evidence, not just an observation.
Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Artemisia arborescens 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.
Signal
Where its DNA was found
How strong is each trace?
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.
