Artemisia michauxiana is a North American species of wormwood in the sunflower family.Calflora taxon report, University of California, Artemisia michauxiana Bess. Michally sagewort, lemon sagewort It is known by the common names Michaux's wormwood and lemon sagewort. It is native to the western United States and Canada.Biota of North America Program 2014 state-level distribution map It grows in mountain talus habitats in subalpine to alpine climates. Artemisia michauxiana is a rhizomatous perennial herb with green, lemon-scented foliage. The plant grows up to 100 cm (40 inches) tall with several erect branches. The leaves are divided into many narrow segments which are hairless or lightly hairy and bear yellowish resin glands. The inflorescence is a spike up to 15 centimeters long full of clusters of small flower heads. Each head is lined with rough purplish green, glandular phyllaries and generally contains pale pistillate and disc florets. The fruit is a tiny hairless achene.Flora of North America Vol. 19, 20 and 21 Page 530, Lemon sagewort, Artemisia michauxiana Besser in W. J. Hooker, Fl. Bor.-Amer. 1: 324. 1833.

The complete instruction manualArtemisia michauxiana 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
Genome size6 493 920 000 bp
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.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Where the DNA of Artemisia michauxiana 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.
