Phlox maculata, common names wild sweetwilliam and meadow phlox, is a species of flowering plant in the family Polemoniaceae, native the eastern United States and introduced to eastern Canada. It is a perennial. Growing to 2-3 ft, this erect, clump-forming herbaceous perennial produces clusters of fragrant, deep pink flowers in summer. The stiff stems are spotted red, hence the Latin specific epithet maculata. It prefers damp, well-drained soil in full sun. It is less prone to powdery mildew than the related Phlox paniculata. The following cultivars have received the Royal Horticultural Society's Award of Garden Merit: 'Alpha' (lilac) 'Natascha' (pink and white) 'Omega' (white with a red eye) Phlox maculata Natascha - Flickr - peganum (1).jpg| Phlox maculata NRCS-1.jpg| Manual of Gardening fig246.png|Botanical illustration A flora of North America (Table 69) (7361660992).jpg|Botanical illustration

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 Phlox maculata has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPhlox maculata 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. Click any value below to see the underlying records and sources.
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 Phlox maculata 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.
